December 4th, 2025 — A day the frontend ecosystem won’t forget. If Log4Shell was Java’s nightmare in 2021, then today’s disclosure of CVE‑2025‑55182 (Next.js counterpart CVE‑2025‑66478) marks the darkest hour of the modern React/Next.js full‑stack era. A CVSS score of 10.0, unauthenticated RCE, and impact across React 19, Next.js 15/16, and any framework implementing React Server Components (RSC). If you're reading this before coffee: drop everything and check your versions. React’s core team has officially confirmed a critical remote code execution vulnerability inside the implementation of React Server Components — and it’s as bad as it sounds. To understand the issue, we need to understand how RSC moves data. React Server Components rely on a streaming, JSON‑like protocol called Flight…  ( 8 min )

Participating in the 5-Day AI Agents Intensive was a transformative experience for me. Before joining, I had only a basic understanding of how AI systems work. But through the intensive, I learned how modern AI agents are designed, how they interact with tools, and how they solve real-world tasks in an autonomous way. One of the biggest takeaways for me was understanding how agents plan, reason, and take actions instead of just answering questions. Concepts like tool use, chaining tasks, prompt design, and structured reasoning helped me clearly see how powerful AI can be when combined with the right workflows. The practical exercises made everything feel real and approachable. I especially enjoyed working with Kaggle’s notebook environment, experimenting with prompts, and seeing how small prompt changes influenced an agent’s performance. It was exciting to watch an AI system break down a complex problem into steps and generate meaningful outputs. Another important learning was the importance of evaluation, safety, and reliability. I understood that building an agent is not just about making it “work,” but making it predictable, responsible, and aligned with user goals. This gave me a more professional perspective on AI development. 5.Overall, this intensive boosted my confidence and motivation to learn further. I now feel comfortable exploring advanced topics like workflow automation, model fine-tuning, and end-to-end agent design. I’m grateful to the Kaggle community and instructors for creating such an interactive learning experience. 6.This journey inspired me to continue building my skills, contribute to real-world AI projects, and keep learning through Kaggle courses.

The success of the logistic regression gave me a confidence boost, but the program's performance felt like a punch to the gut. The naive matrix multiplication module was taking forever to complete even on a small dataset like (321 * 6). No programmer enjoys staring at the console for the program to finish its execution. I have a CUDA-enabled GPU sitting in my machine gathering dust. I had avoided configuring it for development for two years out of sheer laziness. But, to scale up I had to conquer my laziness. I had to make my GPU perform the heavy math. I spent some time searching alternatives. Many search results pointed to ndarray, a high-performance rust library to work with multi-dimensional arrays. It's a great library, but using it out of the box felt like cheating, like another blac…  ( 10 min )

For my cybersecurity masters work, I wanted to go deeper than running tools and reading packet captures. I wanted to understand what was happening inside the packets themselves. Instead of calling Scapy or hiding behind Python abstractions, I decided to build my own packet manipulation library from scratch in Nim. That became NimPacket, and it turned out to be one of the most useful and eye opening projects I have done. NimPacket gives full control of IPv4, TCP, UDP, and ICMP headers. Everything is exposed at the byte level. You can set fields, flip flags, stack layers, serialize to raw bytes, and then parse real traffic back into readable structures. Working at this depth made me understand not just how protocols work but how they fail and how attackers take advantage of them. I included real examples so the library is not just a research exercise. There is a working SYN port scanner, a raw packet sniffer, and an ICMP echo builder. These examples helped validate the code and also give anyone reading the repository a clear idea of how to apply the library in actual security work. It runs smoothly on Kali and makes it easy to build custom packet tools without relying on heavy frameworks. The project taught me a lot about checksum algorithms, endian handling, field packing, and protocol specifications. It also showed me why low level networking is still important for people in cybersecurity. You cannot fully understand network attacks unless you know what each byte represents and why it is there. If you want to see the code or try it out, the repository is here: https://github.com/0x57Origin/NimPacket I am always open to feedback from people who have more experience in systems programming or raw socket work, so feel free to check it out and let me know what you think.  ( 7 min )

Submission for the AI Agents Intensive Course Writing Challenge Introduction I'll be honest—before taking the 5-Day AI Agents Intensive Course with Google and Kaggle, I thought I understood agents. Spoiler: I didn't. My mental model was basically wrapping an LLM in a while(true) loop, adding a few if-statements, and calling it "agentic." Embarrassing in hindsight, but we all start somewhere, right? The past five days have completely rewired that thinking. I've gone from building simple, reactive bots to trying to architect "deliberative" systems that actually plan (and sometimes overthink) their next move.

I have attempted to learn Rust several times in the past. The journey always looked the same: start learning an area of development, implement a few things, understand the concept; and then leave it after some time. This happened more than once, so I decided to try a different approach this time. I was also curious about how AI works. I don't quite like the "magic" of black boxes and machine learning felt like one to me. So, I set out on a new journey: to merge both of my areas of learning in one project. I decided to write a Rust-based ML library. It went well. I spent about a month to get to the point where it can do simple linear regression. But then, due to other priorities, the project went on the back burner, collecting dust. After about 18 months, I found some free time to pursue th…  ( 10 min )

We've all been there. You open a Pull Request, and it's 50 files deep. You spend the next hour commenting on indentation, variable naming, and missing docstrings. By the time you're done, you're exhausted. And that's exactly when the real bugs slip through. I'm talking about the silent performance killers. The O(n) operation inside a loop. The unconstrained file extraction that becomes a Zip Bomb. The full database reload triggered by a single user action. These aren't style issues. They are architectural bottlenecks and security vulnerabilities that linter rules can't catch.

Just a week ago, Google launched Antigravity, and why not give it a try and share my experience? And here I am for this.

This app emulates an artist who can convert your mood into abstract images or videos. Spoiler: this app uses Gemini 3, Nano Banana Pro and Veo, but I'll talk about them in a future article. Let's start with a small presentation about Antigravity. Google Antigravity is an Agentic IDE. It is a fork of VSCode with a dedicated agent section that features models such as Gemini, Claude, and GPT.

it’s a context → space → navigation language. So the ordering rule is: Think of ME as a contextual algebra: State: short-term memory (STM), indexes, encryptedBranches, localSecrets/localNoises, runtime frames Context: the current “frame” (identity focus, effectiveSecret, current pointer target, etc.) Navigation: path composition under the current context. You can group operators by what kind of context they construct: Identity/context focus operators Secret / privacy frame operators Noise / re-root operators Pointer / alias frame operators Derivation operators Query/collection operators tombstones/removes a value under the current context @ creates an identity-focus Thought and updates the active identity frame. _ creates/loads a secret frame and makes selected roots stealth. **~ **changes effectiveSecret lineage. __ binds pointer frame and makes __ptr.* derivations meaningful.

You spent October and November perfecting your holiday campaigns. The sales came through. Your December revenue looked beautiful. Then January hits, and those same customers who couldn't wait to buy from you suddenly act like you never met. Sound familiar? Here's what actually happens: Most brands treat post-holiday email strategy like they're still in November. Another 20% off email. Another "New Year, New You" subject line. Another reason for customers to hit unsubscribe because they're drowning in promotional fatigue after six weeks of URGENT LAST CHANCE FINAL SALE messages. The data tells an interesting story.

From Prompts to Pipelines: What I Learned About Building Real AI Agents When I joined the AI Agents Intensive, I thought “agents” were nothing but just smart chatbots. And by the end, I was building ProdigyFlow — a full multi-agent pipeline that loads raw data, cleans it, analyzes it, creates charts, and finally produces an automated report. This course completely changed how I think about AI. The biggest shift for me was understanding that agents are not one big model — they’re a team. Each agent has a job, its own tools, and a clear role in the pipeline. a Cleaning Agent to fix messy data an Analysis Agent to derive insights a Visualization Agent to generate graphs and a Main File to make them work together smoothly Seeing these parts collaborate felt like building a small company inside Python. There were a lot of behind-the-scenes struggles too: API keys broke so many times we memorized our .env file 😭 GitHub workflows failed at 2 AM for reasons we did not understand We learned how important logs, error handling, and reproducible runs really are Python libraries (Pandas, Matplotlib, tqdm) became our superpowers But every challenge made the final system more real. This project also became a true team win. My teammate Priyamvadha and I figured things out together — fixing bugs, testing agents, and redesigning the pipeline more than once. Here are the project links if you want to explore: https://github.com/komalharshita/prodigyflow https://www.kaggle.com/competitions/agents-intensive-capstone-project/writeups/ProdigyFlow https://www.linkedin.com/in/komalharshita/ Huge thanks to Google, Kaggle, and the mentors for creating this opportunity.

Before we can start creating resources in Microsoft Azure, one of the first concepts to understand is Azure Resource Manager (ARM). ARM is the backbone of how resources in Azure are deployed, managed, and organized. Let's talk about it. Azure Resource Manager is an orchestrator and management layer that sits between users and resource providers, enabling users to create, update, and delete resources in their Azure accounts. Resource providers are services, such as storage or compute, that supply Azure resources. Think of ARM like a remote control for a smart home. Just as a remote allows you to manage various functions like lighting, temperature, and security from one device, ARM acts as the control center, ensuring that all your resources, such as Virtual Machines (VMs), Storage Accoun…  ( 8 min )

Runtime memory handling is a crucial part of writing software, which heavily impacts the performance of your program. I think for every language there comes this layer of responsibility, but how it is delegated between the developer and the language is different. In the case of using C/C++ - memory allocation is totally under the control of the developer. Whereas in languages like JavaScript, Python, Go, Java, where memory is managed - developers rarely need to worry about where an array is stored in memory, it's the duty of the language's runtime system to decide when to deallocate data that is no longer used. And this is where garbage collection comes into play. C# (.NET platform) is known for its heavy GC (garbage collection) of dynamic (heap-allocated) resources. The process is straigh…  ( 18 min )

I slip behind the counter, tie my apron, and take a quick look around at the toppings bar standing like a colorful parade. Pearls, jellies, puddings, popping bursts, the works. Even when I’m tired, that little lineup wakes me up. Opening duties are simple. Shake the containers a bit so everything looks fresh, refill the pearls if they look low, check the ice, and make sure all the teas are brewed and cooled just right. I alw…  ( 11 min )

How the same patterns that saved backend APIs can transform your CLI architecture 💡 TL;DR - The Safe Migration Strategy: Extract commands to external plugins (publish as beta) Add plugins as dependencies in your core (v2.x - zero breaking changes) Gather feedback, iterate, stabilize Remove dependencies in v3.0.0 (breaking change, but prepared) Users install only what they need Result: Safe migration + independent plugin evolution Remember when your CLI was just a little tool with 3 commands? Yeah, me too. Then product asked for "just one more feature"... and another... and another. Now you're maintaining a 50-command behemoth where changing one line breaks three unrelated commands. Welcome to the CLI monolith trap. Here's the thing: CLIs go through the exact same evolution as b…  ( 12 min )

My 5-Day Journey with the Kaggle AI Agents Intensive – What I Learned & Built I recently participated in the 5-Day AI Agents Intensive by Kaggle. This challenge taught me how to understand, build, and deploy AI agents in a simple and practical way. In this post, I am sharing my learning experience and the project I built for the Capstone Challenge. ⭐ Why I Joined the Intensive I joined because I wanted to learn how modern AI systems work—especially agents that can: take actions, understand instructions, interact with tools, and solve real problems. Before starting, I had very little knowledge. But the course made everything easy. ⭐ What I Learned Each Day 📌 Day 1 – Understanding Agents I learned what an AI Agent is, how it works, and why agents are important in real-world apps. 📌 Day 2 – Tool Use I learned how agents can use external tools like: search, code execution, data processing. 📌 Day 3 – Planning I understood how agents break tasks into smaller steps before solving them. 📌 Day 4 – Multi-Agent Systems I learned that multiple agents can work together—each with different skills. 📌 Day 5 – Deployment I deployed my own agent using Kaggle Notebooks and made it publicly viewable. ⭐ My Project: AI Fashion Outfit Recommendation Agent For the final day, I created an agent that recommends outfits based on: user preferences, color choices, style, occasion. The agent analyzes user input and suggests a matching outfit that looks stylish and simple. ⭐ What I Gained from the Intensive Clear understanding of AI agents Ability to build a working agent Knowledge of planning, tool-use, and multi-agent design A complete project to showcase More confidence to explore AI career paths ⭐ Final Thoughts This 5-Day AI Agents Intensive was one of the best short courses I’ve completed. It was simple, beginner-friendly, and focused on hands-on learning. I recommend it to anyone who wants to start learning AI in a practical way. Thank you Kaggle & Google DeepMind for this opportunity!  ( 7 min )

Displaying tabular data on the web can often be a challenge. While Excel spreadsheets are incredibly powerful for data organization and analysis, their native .xlsx or .xls formats are not directly renderable by web browsers. This often leaves developers searching for efficient ways to bridge the gap between rich Excel data and web-friendly formats. The solution? Converting Excel to HTML using C#. This article will guide you through this process, leveraging the robust capabilities of Spire.XLS for .NET to transform your Excel data into clean, accessible HTML. The reasons for converting Excel files to HTML are numerous and primarily revolve around enhancing accessibility and interoperability: Web Display: HTML is the native language of the web.

The 5-Day AI Agents Intensive was honestly one of the most eye-opening learning experiences I’ve had in AI so far. Before this course, I had a basic idea of what “agents” were, but now I understand how they actually think, plan, interact with tools, coordinate with other agents, and solve problems end-to-end. Here are my reflections and key learnings from the week: 🔍 What Concepts Resonated the Most With Me The Difference Between LLMs and Agents I always thought agents were just “smart prompts,” but this course made me see the bigger picture. Tool Use + Planning = Real Intelligence The idea that an agent can call APIs, search, run code, analyze data, and then use that information to make decisions felt extremely powerful. Multi-Agent Collaboration This was my favourite concept — giving different agents different roles and watching them coordinate. Reliability, Guardrails & Iteration Loops Before this, I didn’t think too much about failure modes. 🧠 How My Understanding of AI Agents Has Evolved Before this course: After the course: This shift from prompting to system design is the biggest evolution in my mindset. 💡 Overall Reflections This course didn’t just teach me how to build agents — it changed the way I think about AI systems. I’m excited because agents are clearly the next big thing, and after this intensive, I feel much more prepared to build with them. 🏁 Final Thoughts Huge thanks to the Google × Kaggle team for creating such a well-structured and approachable learning experience. If anyone is curious about agentic AI or wants to start building real autonomous systems, I’d definitely recommend going through the course material on Kaggle’s Discord and Learn Guide. Looking forward to building more agentic workflows and exploring this space even deeper! 🤖✨  ( 7 min )

When the fog rolls in and lightning strikes, you know you're not in Kansas anymore... It started on a dark and stormy night (okay, it was actually a Tuesday afternoon, but let me set the mood here). I wanted to build something that combined my love for atmospheric visuals with practical functionality. What if checking the weather could be... spooky? Enter the Eerie Weather App — a 3D weather visualization experience where a haunted floating house reacts to real-time weather conditions from cities around the world. Rain? The skies darken and droplets fall. Thunderstorm? Lightning cracks across the sky with an eerie glow. It's like having your own personal haunted house that tells you whether to bring an umbrella. The floating house awaits, shrouded in eternal twilight... Every good haunted…  ( 10 min )

Taking part in the 5-Day AI Agents Intensive Course was a transformative experience that reshaped how I think about autonomous systems. Each day blended discussion, experimentation, and practical exercises, giving me a grounded understanding of how AI agents operate in real scenarios—from simple task execution to more cooperative multi-agent interactions. Key Takeaways A major insight for me was recognizing how different AI agents are from conventional chatbots. Rather than waiting for prompts and responding, agents can draw on tools, gather information, and make step-by-step decisions to work toward a goal. Seeing this distinction in action helped me appreciate how agent-based systems can support more dynamic problem-solving. I also gained a clearer picture of how memory and coordination …  ( 7 min )

I realize I'm building plugins for a "niche within a niche"—using Neovim for Unreal Engine C++ development. But honestly? It's becoming surprisingly capable. This week, I shipped some massive updates to the UnrealDev.nvim ecosystem. From Perforce integration to a wizard for generating UPROPERTY macros, here is what’s new! Health Checks for Peace of Mind :checkhealth UnrealDev I added a health check command to verify that your Unreal Engine development environment is set up correctly.

This is a submission for the Google AI Agents Writing Challenge: Learning Reflections* The AI Agents Intensive has honestly been one of the most eye-opening learning experiences I’ve had in a long time. When I joined, I had a basic idea of what AI agents were—but I definitely didn’t understand how they think, how they make decisions, or how much autonomy they can actually have. This course completely changed that. Concepts That Truly Stuck With Me are: (1) Reasoning Loops & Agent Architecture: Understanding frameworks like React and Reflexion helped me see the “mindset” behind an agent—how it observes, reasons, plans, and then acts. It felt like I was finally seeing the blueprint of intelligence. (2) Tool Use: This was a big “aha” moment. Realizing that agents become powerful when they can…  ( 7 min )

Or: How I Learned to Stop Worrying and Love the Compiler 🦀 It was 3 AM. I was staring at my screen, watching npm install crawl through its 47,000th dependency. My React app needed one simple date picker. One. The node_modules folder? 1.2GB. The actual code I wrote? 200 lines. That's when I decided: enough is enough. Let's be honest about what we've normalized: "Just run npm audit fix" — Translation: Play Russian roulette with your dependencies and pray nothing breaks. "Works on my machine" — Because somehow, in 2025, we still can't reliably reproduce builds. "Add @ts-ignore here" — TypeScript's way of saying "I give up, you're on your own." "node_modules is only 800MB" — Said with a straight face, as if that's acceptable for a todo app. We've gaslit ourselves into thinking this is fine. I…  ( 9 min )

Day 3: Multi-Agent Systems - The Supervisor Pattern Welcome to Day 3. We have a single agent that can use tools. But as tasks get complex, a single prompt becomes overwhelmed. It's hard to be a "Researcher, Writer, Editor, and Coder" all at once. The solution is Multi-Agent Systems. We break the brain into specialized distinct personas. We will build a graph where two agents collaborate: Researcher: Has access to search tools. Its system prompt is "You are a researcher...". Writer: Has NO tools. Its system prompt is "You are a writer...". They communicate by adding messages to the shared State. We use a helper function to create nodes. Notice how we bindTools only to the Researcher. The Writer doesn't even know tools exist, which prevents it from hallucinating tool calls. const createA…  ( 7 min )

Day 2: Introduction to LangGraph - From Chains to Agents Yesterday, we built a Chain. It was a straight line: Input -> Retrieve -> Answer. This is where LangGraph comes in. It treats your AI application as a Graph (nodes and edges) rather than a Chain (a list of steps). In a Chain, data flows from one step to the next like a bucket brigade. In LangGraph, there is a central State object that everyone reads from and writes to. It's like a shared whiteboard. // The State is just a list of messages import { MessagesAnnotation } from "@langchain/langgraph"; // MessagesAnnotation is a pre-built state definition for chat apps. Nodes are just JavaScript functions. They take the current State, do some work, and return an update to the State. const agentNode = async (state) => { // Read the his…  ( 7 min )

Day 1: Foundations of Agentic AI - RAG and Vector Stores Welcome to the first day of our 4-day series on building Agentic AI applications with LangChain and LangGraph. Over this series, we will evolve a simple script into a sophisticated, human-in-the-loop multi-agent system. Today, we start with the bedrock of modern AI apps: Retrieval Augmented Generation (RAG). Large Language Models (LLMs) like GPT-4 are frozen in time. They don't know about your private data, your company's wiki, or the news from this morning. If you ask them about it, they might "hallucinate" (make things up). RAG is a technique to "inject" knowledge into the LLM's prompt before it answers. It works in two phases: Ingestion: Preparing your data for search. Retrieval: Finding the right data and sending it to the LL…  ( 8 min )

Day 4: Production Patterns - Persistence and Human-in-the-Loop Welcome to the final day. We have a smart team of agents. But in the real world, scripts crash, users get distracted, and sometimes the AI makes a mistake that a human needs to catch. Today we cover two critical features for production apps: Persistence (Memory) and Human-in-the-Loop. Standard scripts lose all memory when they finish. LangGraph has a built-in Checkpointer system. It saves the State to a database (or memory) after every single step. This allows: Long-running conversations: Like ChatGPT threads. Resume on failure: If the app crashes, you can reload the state and continue. Time Travel: You can actually go back to a previous step and try a different path! import { MemorySaver } from "@langchain/langgraph";…  ( 7 min )

See Through Walls: AI's New Eye on Occluded Motion Ever struggle to get accurate motion capture when hands are intertwined, hidden behind objects, or even just slightly out of view? Standard computer vision systems often falter when faced with these real-world occlusions, leading to jerky animations, unreliable robotic control, and frustrating user experiences. But what if an AI could "see through" these obstructions and accurately track movement even when parts are hidden? The solution lies in a novel approach to visual feature extraction: a deformable state space model. Imagine it as a highly adaptable, intelligent filter that not only analyzes local features (like the edge of a finger) but also dynamically adjusts its focus to gather contextual information from the entire scene.

Kling AI is making waves in the generative AI space, pushing the boundaries of what's possible in video creation. Their latest innovation, VIDEO 2.6, is not just another iteration; it represents a significant leap forward, particularly with its groundbreaking feature: native audio. This release signals a pivotal moment for multimedia content generation, moving us closer to truly immersive and realistic AI-generated experiences.\n\nWhat exactly does \"native audio\" mean for VIDEO 2.6? Traditionally, AI video models often generate visuals, and audio is then a separate, often manual, post-production step or generated by a different model and then synched. This approach can lead to disjointed experiences, where audio and video don't feel organically connected. VIDEO 2.6 changes this by integr…  ( 11 min )

Instagram rolled out Collabs 2.0 in late 2025, and for once, the update actually matters. The original Collabs feature (remember that from 2021?) let two accounts co-author a post. Both profiles appeared in the header, both got the engagement metrics, both celebrated when it went viral. Simple enough. But it had limitations that made partnership content feel like trying to coordinate a group project where half the team can't access the shared document. Collabs 2.0 changes that. And if you're doing any kind of brand partnerships, influencer marketing, or just trying to grow your account through collaborations, you need to understand what's different. Let's start with what Instagram fixed, because the original version had some genuinely annoying gaps. First, you can now add up to four collab…  ( 13 min )

TL;DR: Se você está integrando IA (LLMs, etc.) no backend e fazendo várias chamadas externas de forma sequencial, está jogando tempo fora. Ao aplicar noções básicas de concorrência e paralelismo (Promise.all, limitação de concorrência, separação entre ingestão externa e leitura paginada), é perfeitamente plausível reduzir um endpoint de ~40s para ~8s sem trocar de stack — só usando fundamentos de computação. Nos últimos anos, ficou relativamente fácil “plugar” IA generativa em qualquer backend: basta chamar uma API, mandar o texto e receber a resposta. O problema é que, em produção, esse “basta chamar” rapidamente vira 40 segundos de espera num endpoint que deveria responder em poucos segundos. O que separa um endpoint lento e frágil de um endpoint robusto e rápido, especialmente quando en…  ( 14 min )

Publicado primeiro na newsletter do The Thinking Engineer. Se quiser receber o próximo no seu e-mail, se inscreva. A cena é comum. Você entra na reunião da sprint planning, ainda organizando mentalmente o backlog, quando alguém de produto abre a call e solta: Pessoal, precisamos colocar isso no ar até sexta. O slide aparece. Por três segundos, a sala fica num silêncio estranho. E é aqui que a engenharia começa a perder força: o time entra no modo executor antes mesmo de entender o problema. Esse pequeno desvio — quase imperceptível — é responsável por grande parte da dívida cognitiva, decisões de baixa resolução e entregas que resolvem sintomas em vez de causas. Quando reli O Programador Pragmático, uma frase me acertou como um lembrete incômodo: “Bons engenheiros não coletam requisitos — …  ( 9 min )

As an engineering manager responsible for keeping serverless, event-driven systems alive, I’ve learned to fear green dashboards. There is no worse feeling than seeing your main status page happily report “99.9% up” while Slack is full of screenshots from customers who can’t check out, can’t pay, or can’t log in and a senior leader is asking, “Why does everything look fine if the business is clearly on fire?” That’s the core problem: Global availability is a vanity metric. It smooths out the spikes. It tells you the system is fine, but it doesn’t tell you if the business is fine. In site reliability engineering (SRE), we like tidy global SLIs because they compress a lot of behaviour into one number. But that compression is exactly how pain gets hidden. If you have 1,000,000 requests and 1,0…  ( 11 min )

In the previous blog it's mentioned some benefits about of IaD and how this concept this wide used in cloud native, let me write in this post about KCL for create anything declarative manifest. KCL is an open source configuration and policy language, currently a Cloud Native Computing Foundation (CNCF) Sandbox project. It was created to overcome the limitations of static formats like YAML or JSON, especially in complex cloud-native environments. To achieve this, KCL combines the simplicity of a data language with the power of a modern programming language, allowing you to create abstractions, enforce validations through a constraint system, and automate large-scale data management. In short, you write in KCL to generate configurations for tools like Kubernetes and any tools that use yaml i…  ( 10 min )

Motivações e Melhores Práticas de Utilização Introdução e Objetivos Este artigo aborda o log sob a perspectiva de depuração e monitoramento de sistemas em ambientes de desenvolvimento e produção, distinguindo-se dos logs de auditoria. O objetivo principal da ferramenta de log é auxiliar no acompanhamento da execução do sistema, facilitando a identificação de erros e indicação de falhas críticas. A técnica de log consiste na geração de registros em diferentes destinos (arquivos, console, sistemas centralizados) para que desenvolvedores e analistas de suporte obtenham informações sobre processamentos importantes ou ocorrências de erros em produção. O monitoramento de logs é essencial para o diagnóstico de problemas. Tentar descobrir um bug em produção sem logs é como andar no es…  ( 21 min )

Most teams assume retrieval quality drops because embeddings or vector stores are failing. Chunking appears straightforward. Slice text into pieces, embed, and retrieve. This post walks through the root causes, detection signals, and stabilizing fixes. Short Answer Retrieval usually fails because chunk boundaries shift over time in ways nobody notices. What Breaks Chunking in Real Systems The issues below appear repeatedly across audits, ingestion pipelines, and multi-format corpora. Boundary Drift: Minor formatting or structural differences cause chunk boundaries to fall in new regions, breaking previously stable embeddings. Semantic Fragmentation: Chunks split mid-concept or mid-section, separating meaning that should stay together. Overlap Inconsistency: Overlap logic shifts across form…  ( 8 min )

I’m building OCR Trips — an obstacle course race trip planner that helps you: Discover races Plan trips Budget flights, hotels, and race fees in one place The “app” part (accounts and trip plans) runs on Supabase. Ow, yeah! 🏄 But for the MVP content, I didn’t want everything living in a database. Users would manually add races they know. That was the original idea: a lightweight trip planner where you plug in your next OCR and we help with flights, hotels, and budget. Then I thought: what if someone doesn’t have a race yet and needs help finding one? So I expanded the site with Obstacle Course Race Calendar — a public directory where anyone can: Browse obstacle course races by country and by city. See nearby airports and rough travel ideas Check typical weather for race dates Filt…  ( 8 min )

This is a submission for the Google AI Agents Writing Challenge: [Learning Reflections] This article was originally published on FAIRLYZ Knowledge Base. Nov 13, 2025 — by Patricia Buendia in AI, AI Governance, Data Security The Google AI Agents Intensive Course (First 5DGAI) debuted in March 2025 and returned in November 2025 (second 5DGAI), offering developers a front-row seat to the rapid evolution of agentic systems. The First 5DGAI course focused on foundational skills: writing prompts, training agents, customizing them using Retrieval-Augmented Generation (RAG), and deploying them via MLOps. Participants learned to fine-tune models and integrate external knowledge sources to improve agent performance. By November, the second 5DGAI curriculum had advanced significantly. Developers were…  ( 7 min )

Okay, here's the next part. And now I gonna talk about features that cross though the whole app such as: exceptions, dialogs, global events etc. I mean features whose behavior depends on others.The main concept is making some SSOT for global events and subscribe to it in the main module. And the Flows will help us for that goal. For this purpose I'll use SharedFlow. It was especially created for this kind of cases. Platform is only Android (not CMP/KMP) Our project is multi-module The features have their own screens Any feature can send some trigger The features are independent on each other As usual domain module is independent on each other. It's a keeper of interface GlobalRepository and enum GlobalEvent interface GlobalRepository { val eventFlow: SharedFlow fun se…  ( 7 min )

TL;DR Idempotent or fully reproducible Dockerfiles are frequently promoted as a best practice, but in most real-world engineering environments they are not the right objective. What teams actually need are: (1) immutable, traceable artifacts stored in a registry, and (2) regular CI rebuilds that continuously pick up security patches and updated dependencies. Idempotent rebuilds provide relatively little operational value when the original image artifact is preserved and addressable by digest. Reproducibility is still useful in specialized domains (regulated, research, high-assurance), but for mainstream application development it adds cost and complexity without commensurate benefit. Most Docker tutorials and security guides assert that building an image “should be idempotent and reproduci…  ( 9 min )

How to Build a Voice Bot for Car Dealerships Using VAPI TL;DR Most car dealership voice bots fail when customers ask off-script questions about inventory or financing.

You remember that story I told you about avoiding Kubernetes for 2 years? The one where I said I was "intimidated" and then a client issue forced me to learn it and suddenly everything clicked? Yeah, I made it sound inspiring. Motivational even. Here's what I didn't tell you: I didn't just avoid Kubernetes because I was intimidated. I avoided it because every time I tried to learn it, I failed so badly that I questioned my entire career. That "pressure forced me to learn fast" moment? That wasn't a movie montage of me powering through with determination. It was me sitting in front of my laptop at 2 AM, tears running down my face, genuinely asking God if I was smart enough to do this job. The first version of this story was the polished version. This is what really happened. The part I was …  ( 13 min )

A cluttered kitchen can slow down your workflow, just like a messy codebase slows down development. Developers know the value of organization, automation, and efficiency. The same principles apply to your home workspace and kitchen. Thoughtful kitchen accessories can help streamline daily routines, reduce wasted time, and improve focus — lessons developers can relate to. Developers thrive in clean environments. A messy kitchen sink, like a cluttered development environment, creates unnecessary friction. Magnetic sponge holders, utensil caddies, and drying racks keep essential tools in order. Developers can relate this to keeping IDEs, repositories, and scripts neatly arranged. The principle is the same: an organized setup reduces errors and improves efficiency.

I have always been fascinated by Computer Science and technology. Like many others, I have been using tools like ChatGPT for a while now. I used to think AI was just about asking questions and getting answers. But after exploring the Kaggle AI Agents Intensive, I realized that the future of tech is much bigger than just "smart chatbots." What Changed My Mind? LLMs talk: They are great at predicting text and giving information. Agents act: They can actually do things. The concept that an AI can use "Tools"—like searching the web or running code—was really exciting to learn. It feels like giving the AI a pair of hands to interact with the digital world. The Logic Behind the Magic Looking Ahead This was a short but powerful learning experience. I can’t wait to learn more and eventually build my own agents!  ( 7 min )

First: what is Notte? Simply put, Notte provides a platform to build and deploy web agents that don’t break. By turning complex and repetitive web tasks into reliable self-healing workflows, businesses can scale automation with confidence. Notte exists because the web is still designed for humans, not agents. Pure web agents can navigate it, but while they excel on benchmarks, they’re unreliable and costly in production. Traditional scripts are faster and cheaper, but a single website tweak can break them entirely. Notte’s answer is Hybrid Agent Workflows: freeze the routine into deterministic steps; reserve LLMs for when adaptive reasoning is required. If a page changes out of hours, your flow doesn’t wait on you to redeploy - the agent adapts at runtime and carries the task to completi…  ( 9 min )

Over the last couple of years, fitness has become a huge part of my life. I lost 45 kilograms through training, daily cardio, eating better, and staying consistent with my supplements. And even though I was motivated, there was one simple thing I kept messing up: I couldn’t remember which supplements I had taken each day. Some mornings I’d double-dose my omega-3 without realizing. Some nights I’d remember I forgot my multivitamin. Some days I’d start creatine loading… and then completely forget the next day. It sounds small, but when you’re serious about your fitness, these details matter. And I hated the feeling of being inconsistent after working so hard. That’s how GymDose started — not as an app for the world, but as an app for me. I tried using habit trackers, to-do apps, reminder a…  ( 8 min )

Introduction — Why I Joined the Agents Intensive When I enrolled in the Kaggle AI Agents Intensive, I had one goal: As someone working at the intersection of data engineering and healthcare, I wanted to see whether agentic architectures could meaningfully improve clinical research, where slow evidence synthesis costs time, money, and sometimes lives. The answer turned out to be yes, and the Intensive course gave me the exact structure, concepts, and building blocks I needed. The Problem — Healthcare Research Overload Clinical researchers are drowning in papers. This creates four fundamental problems: Too much literature to scan manually 2.Fragmented tools (PubMed to PDFs to spreadsheets) 3.No structured memory across searches 4.No reproducibility when using typical LLM assistants Healthcar…  ( 8 min )

Software development is rarely a solo activity. Each developer brings skills, experience, and insights — but the true power of a team comes from how those contributions interact and amplify one another. When a team is aligned around shared design principles, domain understanding, and goals, the result is more than the sum of its parts: 1 + 1 can equal 3. Continuous Integration (CI) was originally designed to support that kind of teamwork. By integrating code frequently, running automated tests, and catching issues early, it allowed developers to collaborate confidently without stepping on each other’s work. Over time, however, the industry’s use of merge requests, quality gates, and strict CI pipelines drifted from enabling collaboration to enforcing compliance. CI became a mechanism to in…  ( 10 min )

I have an app on Railway that uses SQLite, and for a while I was manually SSHing into my project to query data whenever I needed it locally. What started as occasional checks became a daily interruption. When I decided to automate this with GitHub Actions, I expected a quick win, but I discovered that what worked on my local machine failed in CI. Even my favorite AI tools, goose and Claude Code, couldn't quite figure it out. They claimed the issues I encountered were underdocumented. After more time than I'd like to admit, here's what I learned. I chose SQLite because it was lightweight and I only needed it temporarily, but Railway doesn't expose SQLite databases to the internet (which is good). Unlike Postgres or MySQL, there's no connection string or public endpoint, so the database file…  ( 8 min )

Disclaimer: this article shows my opinion and is not intended to be an absolute truth. During my short career, I saw countless times a developer picking at the code and yelling or mumbling to himself "what a shitty code". We all have gone through it, me the first. Even Robert C. Martin considered it as a metric of "bad code" in the book Clean Code ! Apart from the disappointment, this expression brings no constructive value: no explanation, no will to help your colleague be a better professional and is pure judgment. Moreover, it is also a dangerous expression because it can bring tension in the team. How your colleague would react if you say that to the code he just wrote ? Even if we look for less ego in our sector, no one would be happy to hear that. Even if you are in the perfect te…  ( 9 min )

Anthropic didn't just buy a fast JavaScript runtime. They bought the one missing piece that turns Claude Code from a clever tool into a full-stack engine for how software will be built in the next decade. Yes, it's true. It's about control of the runtime layer at the exact moment AI agents begin writing, testing and shipping most of the world's code. Let's get straight to the point. Anthropic acquired Bun because Claude Code hit a billion dollars in revenue in six months but depended on a runtime they didn't control. Bun needed Anthropic because despite 7 million monthly downloads, it made zero revenue. This deal creates agent-native infrastructure where AI agents write code using a fast, single-binary runtime, fundamentally changing how software is built. Anthropic now controls both the r…  ( 10 min )

The Silent Killer of Developer Productivity As a developer, I know the frustration of waiting for a build. You push your code and instead of just looking at the screen, I switch to another task, lose context, and by the time the CI pipeline finishes, you've forgotten what you were working on. In my customer's case, this frustration had a very specific 30 minutes per build, mostly spent downloading Maven dependencies. Their setup wasn't unusual. They had GitHub Actions self-hosted runners spinning up on Amazon EKS for each triggered CI job. These runners needed Maven packages stored in their on-premises Nexus repository, connected via VPN. The architecture made sense on paper—until they measured the actual latency impact. The math was crystal clear. With dozens of developers triggering h…  ( 11 min )

Advertisers today pay an invisible 50% "AdTech Tax" on every dollar spent. For every $100 you put into programmatic advertising, less than $50 actually reaches the publisher. The rest is devoured by a murky supply chain of DSPs, SSPs, and data fees. For D2C brands operating on razor-thin margins, this inefficiency is a silent killer. The Core Concept: Traditional AdTech strategies focused heavily on media buying efficiency—bidding cheaper and targeting better. In 2025, with privacy regulations (GDPR, CCPA) and signal loss (cookie deprecation), the leverage has shifted. The new AdTech strategy is Creative Utility: using AI to generate high-volume, high-relevance ad creatives that lower CPA through engagement rather than just bidding mechanics.

The Problem We're Solving Let's be honest - mobile apps need to work offline. House hunters are going to be in basements, on subways, or in areas with terrible WiFi. They'll want to add house listings or take notes during open home viewings, and they shouldn't have to wait for a network connection. So how do we build an app that works seamlessly offline, but also syncs everything back to the server when connectivity returns? That's what we're diving into in my new app "MyNextHome". Our house hunting app has three main pieces: HousesContext - The brain that manages all the houses and handles syncing Add/Edit Form - Where users create new listings House Details Screen - Where users take notes on each house Everything is stored locally first (using AsyncStorage), then synced to the server w…  ( 9 min )

Introduction: The New Frontier of Product Ownership Suzanne Alipourian-Frascogna emphasizes, “If you own the product, you own the threat model too.” This shift reflects a broader reality: cybersecurity is now inseparable from product ownership. This article explores how product managers can strengthen digital ecosystems by integrating security principles directly into product strategy. When PMs take the lead on cybersecurity, the result is not only safer products but more scalable and trusted ones. Traditional development processes often treat cybersecurity as something to evaluate near the end—an item on a pre-launch checklist or a concern revisited only after a breach. This reactive approach is costly, inefficient, and dangerous in a world where threats evolve continuously. According to …  ( 9 min )

As a designer working on a Mac, I’ve always felt like the odd one out when it comes to remote USB access tools. Most of the well-known utilities I tried in the past were focused almost entirely on Windows — including the one I used for years from usb-over-ethernet When I switched my main workstation to macOS, that old software basically became useless. It didn’t receive updates anymore, support disappeared, and on top of that, my Linux render nodes still had no way to access my input devices remotely. At some point I started searching for alternatives and eventually came across USB Network Gate. I wasn’t expecting much, but it turned out to be one of the few options that actually works across different operating systems without strange workarounds. Right now, I can connect my 3D mouse or Wacom tablet to my Mac and let my Linux workstation pick it up over the local network. Nothing fancy — it just shows up and works, even though the systems are different. For my setup, that was exactly what I needed. If anything changes or I run into new issues, I’ll update this post. And if anyone knows of any other working alternatives for macOS + Linux, I'd be happy to try them and share my impressions later.  ( 6 min )

We are currently witnessing a fragmentation crisis in the AI ecosystem. You have your Logic Layer (the LLM—Claude, GPT-4, Gemini), your Interface Layer (Cursor, Windsurf, Claude Desktop, n8n), and your Data Layer (Postgres, local files, internal APIs, Slack, GitHub). Until recently, connecting these layers required a brute-force approach. If you wanted your LLM to access a database, you wrote a specific function call. If you switched from OpenAI to Anthropic, or from a Python script to a visual builder like Flowise, you often had to rewrite the integration logic. We have been treating LLMs like isolated processors, manually soldering wires to every peripheral device we want them to touch. The Model Context Protocol (MCP) changes this paradigm entirely. It is the architectural equivalent of…  ( 12 min )

The Problem Imagine you're building a search feature for a list of 2,000 products. Every time a user types a letter, your app filters the entire list and re-renders it. What happens? The input lags. The user's typing feels sluggish and frustrating. This is a common problem when dealing with heavy updates in React. What if we could tell React: "Hey, updating this list is important, but keeping the input smooth is MORE important"? That's exactly what useTransition does. useTransition is a React hook (introduced in React 18) that lets you mark certain updates as non-urgent. This means React can prioritize user interactions (like typing) over heavy rendering tasks (like filtering a huge list). const [isPending, startTransition] = useTransition(); startTransition: A function that wraps non-u…  ( 8 min )

If you’ve ever worked with LLMs in real applications — especially with LangChain + TypeScript — you probably know the frustration: Broken JSON Extra text wrapped around JSON Random “creative” outputs Parsers blowing up in production I’ve personally gone through it all. Next.js, LangChain, Supabase Vector Store, Pusher, and more — I tried every prompt trick to force LLMs to follow a strict JSON structure. I told the model: “Return valid JSON only.” I added strict instructions. Nothing worked reliably. Prompts alone can never guarantee valid JSON. LLMs aren’t designed to obey formatting rules consistently. 2025, the solution finally became production-ready: The Fix: LangChain .withStructuredOutput() + Zod This combination forces the model to return: 100% valid JSON Fully typed data Schema-safe responses No extra text No formatting issues And the best part?

I know how devs building web apps often need to embed dashboards and are looking for ones that are easy to integrate and include interactivity. Something else to consider is low-cost scalability, meaning low resource costs. Serverless apps are the answer. One of them is called StyleBI, and you can embed interactive dashboards directly into your React app, enforce row-level security per user, and scale elastically without managing servers or paying for instances when no one is using the dashboards. It connects seamlessly to common data sources like AWS, Postgres, or Snowflake, giving your users real-time insights while keeping operational overhead low. Here’s a simple example of embedding: `import React from "react"; const Dashboard = () => { export default Dashboard; ` The idea is that with serverless BI you can focus on building features and delivering insights rather than managing infrastructure or wasting money. There is an open source version on GitHub.  ( 6 min )

Sales teams waste hours every day jumping between Slack, email, and their CRM just to figure out what happened with a deal. Who talked to the client last? What did they say? The context is scattered everywhere. Apollo.io solved this by making its CRM truly collaborative. Sales reps can see exactly who's working on what, leave contextual comments right on deal records, and get notified when something important happens. No more hunting for information or stepping on each other's toes. The thing is, building real-time collaboration isn't simple.

🧪 API Testing with Postman and Newman Testing APIs has become an essential part of modern software development. Before connecting the backend with the user interface, we need to make sure every endpoint behaves as expected — returning the correct data, handling errors properly, and performing under different conditions. In this guide, we’ll explore how to apply Postman and Newman to automate API testing through a simple and realistic example. APIs are like bridges between different systems. When one part of an app sends a request, the API is responsible for sending the correct response back. If something fails here, the entire application can break. API testing ensures that: Each endpoint returns the right HTTP status code. The JSON data structure is consistent. Response times st…  ( 8 min )

Introduction Terraform provides a powerful configuration language that allows you to build reusable, scalable, and environment-aware infrastructure. Three of the most useful features within Terraform’s expression system are conditional expressions, dynamic blocks, and splat expressions. Understanding these three concepts helps you write cleaner, more flexible code while avoiding duplication and complexity. This blog explains each expression in detail, including when to use them, when not to use them, and how they work together. Conditional expressions return one of two values depending on whether a given condition is true or false. condition ? true_value : false_value If the condition is true, the first value is returned. If the condition is false, the second value is returned. Similar …  ( 8 min )

These models are already reshaping industries like advertising, gaming, fashion, and science. But creating images is the easy part. Judging their quality is much harder. Human feedback is slow, expensive, biased, and often inconsistent. Plus, quality has many faces: creativity, realism, and style don’t always align. Improving one can hurt another.

For many engineering leaders, the observability bill has become one of the largest infrastructure expenses. OpenAI reportedly spends $170 million annually on Datadog alone. While most companies aren't operating at OpenAI's scale, teams consistently report that observability tools consume a significant portion of their total cloud spend, and the trend only goes in one direction: up. The root cause? SaaS platforms charge per gigabyte ingested, per host monitored, or per high-cardinality metric tracked. The more visibility you need, the more you pay. You're stuck choosing between understanding your systems and staying within budget. This model prevents you from being able to “send everything.” You can break this cycle by changing how you pay for observability. Instead of variable costs tied t…  ( 15 min )

When you start out learning object-oriented programming (OOP) in Python, inheritance feels like the obvious way to reuse code. You build a base class, extend it, and reuse its behavior. But as your software grows, you might start noticing that inheritance introduces tight coupling, rigid structures, and eventually... a mess. This post is about why composition is often a better choice than inheritance in large-scale Python systems, especially when you're building backend applications. We’ll start from the basics, then go into real-life backend scenarios to show how composition can help you write cleaner, more maintainable code. Inheritance means creating a new class that is a type of another class. It forms an "is-a" relationship. The child class (subclass) automatically gets the properties…  ( 9 min )

As developers, we spend our days solving complex problems.

Every context switch costs focus. I kept thinking: why can't I just type what I'm thinking and get the answer? Most calculators are built for numbers, not questions. You can't type $150 + 20% tax into a standard calculator. You have to: Type 150 Multiply by 0.20 Add the result to 150 Remember what you were doing before And for currency? Time zones? Date math?

AttributeError: 'int' object has no attribute 'title' in python This error means you’re calling the string method .title on a value that is actually an int, not a str. In other words, somewhere a variable you expect to be text holds a number instead. Variable shadowing. A name you used for a string earlier was reassigned to an integer, so later obj.title tries to run on an int. For example: name = "alice"; name = 5; name.title() → error. This commonly happens when reusing names like file, time, or data for different types at different points of the code. Wrong data shape. You indexed or pulled data from a dict/list/JSON where some items are ints and others are strings, then you applied .title blindly to all items. Type assumptions.

How to deploy a fully HA (High Availability) cluster completely isolated from the public network, managed via a Bastion? In the Cloud Native world, ease of access is often the norm. But for critical environments or simply to have complete control over your flows, isolation is king. My objective was clear: build a Kubernetes cluster that "doesn't talk to strangers". No direct exposure to the Internet, strict control of inputs/outputs through a single gateway, and secure administration. To achieve this, I chose Talos Linux (for its immutability and security) hosted on Proxmox (with a dedicated VXLAN network). Here's how I transformed three bare VMs into a High Availability (HA) cluster behind a Bastion. Before running any commands, let's set the stage. The challenge here isn't Kubernetes, …  ( 13 min )

I’m excited to join this community! I’m Amna, a tech learner who enjoys experimenting with AI tools, writing clean content, and building simple things that help people work smarter. Over the past few months, I’ve been exploring different AI writing and text-processing tools.

Peace Thabiwa SUMMARY LAW-M is a multi-layered cognitive–mechanical theorem that defines how humans, machines, and environments exchange, predict, and synchronize time. It formalizes a truth modern engineering treats as an afterthought: every failure in high-speed systems is a failure of timing alignment, not a failure of components. In LAW-M, timing is not just a number — it’s a vector. H-Vector: Human biomechanics, cognitive delay, internalized time, sensorimotor loops V-Vector: Vehicle mechanical latency, drive-train inertia, response curves E-Vector: Environmental volatility, friction coefficients, atmospheric shifts LAW-M explains how these three timing worlds interact, fuse, drift, and misalign — and how the MindEye cognitive engine can stabilize them through patterned training, simu…  ( 134 min )

I grew up reading the gripping and petrifying narratives of R.L. Stine and spending way too much time playing story-driven video games. Now that I'm older, I've gotten into the TTRPG space because it hits a certain je ne sais quoi that tickles my lizard brain. I've also found that I'm not as good at coming up with ideas for adventures as I used to be. For anyone who has ever sat behind you laptop screen and keyboard, staring into the blinking cursor, you know the struggle: you have a cool concept, like "a Cyberpunk heist in a floating city," but when you try to flesh it out, you hit a wall. Naturally, we now can turn to AI for help. But here's the problem: standard LLMs are great at hallucinating generic tropes. You ask for a "scary forest," and you get the same old "twisted trees and whis…  ( 11 min )

If you’re running a website in 2026, you probably care about security. You might have HTTPS, HSTS, CSP, maybe even a bug bounty program. But there’s a tiny text file most sites still miss: /.well-known/security.txt It’s a simple file that tells security researchers how to contact you if they find vulnerabilities on your site. In this post, I’ll explain: What security.txt is (in human words) Why it matters even if you don’t run a big security team What goes inside the file How to generate one in a couple of minutes using a browser-based tool How to deploy it on common setups (static site, Laravel/PHP, .NET/IIS, etc.) No security team required.

Building a production-ready multi-LLM platform in weeks, not months When I set out to build Mirmer AI, I had an ambitious vision: resurrect the 400-year-old peer review process that built modern science, and run it at machine speed with AI models. The concept was simple but the execution was complex: Stage 1: Multiple AI models respond independently Stage 2: Models anonymously peer-review each other's responses Stage 3: A chairman model synthesizes consensus But here's the reality check: I'm a solo developer.

As developers and engineers, we're obsessed with building products that solve real problems. We live in a world of logic, APIs, and elegant code. So when 'marketing' comes up, it's easy to tune out the fluff. But what if we looked at marketing—specifically customer stories—as the ultimate validation of our work? A great video testimonial isn't just a sales tool; it's a narrative about a problem solved. It's the human-centric output of our technical input. It’s proof that the product works. Let's deconstruct seven examples from top SaaS companies and see what we, as builders, can learn from them.

The article was initially published on the Skyvia blog. Data’s all around us — from CRM systems and cloud apps to spreadsheets and data warehouses. But when your team’s wrangling numbers across 15+ platforms and spending more time copy-pasting than analysing, the real issue is a broken data flow. Here’s a quick breakdown of how to pick a pipeline tool in 2025, what to look for — and where a no-code alternative like Skyvia can really ease the load. A data pipeline is simply the process of moving data from one place to another, often transforming it along the way so it ends up clean, consistent and ready to use. In practice this means: grabbing data from SaaS apps, databases, APIs or spreadsheets cleaning, normalising or reshaping it (dedupe, convert, standardise) loading it into a des…  ( 9 min )

In the early days of microservices, “small and independent” sounded simple enough. Teams broke apart their monoliths, spun up a dozen new services, and declared victory. Then came the reality: too many services, endless integration pain, duplicated logic, and distributed complexity that nobody asked for. Somewhere along the way, the word “micro” became misunderstood. It was never about size - it was about boundaries. So, what does “micro” really mean? Let’s start with a misconception: microservices are not defined by lines of code. A microservice with 500 lines can still be too big - if it mixes domains. The essence of a microservice lies in independence: It can be developed and deployed independently It owns its data It exposes clear contracts It doesn’t need other …  ( 8 min )

As a developer, I frequently need to quickly track a list of tasks, and most of the time, I don't need the full-featured project management capabilities of solutions like Basecamp, Notion, Todoist, and others. I tried almost every tool, from Apple Reminders to Basecamp, but I either failed to manage my tasks properly or the features and complexity of the bigger tools overwhelmed me. To solve this, I created GoalHappy, a simple task manager app. Features No login required, start managing your tasks right away If you need cloud sync, create a free account and get 50 tasks synced for free PWA - Use cross-device (offline), and get your tasks synced when online If you need to manage a lot of tasks and lists, and also want to share the lists for collaborative work, the paid version is just $2 per month or $18 per year I believe that, as a developer, you will love GoalHappy.

Well, while browsing the functionalities of a well-known TF2 trading site, I discovered that old habits die hard. How did I find the bug? On the Item page there is a navigation feature allowing users to jump to a specific page of listings. Pressing the "..." button triggers a pop-up where you can manually input the page number. Naturally I wondered "Does it trust my input?". Instead of a number, I inputted the character "e".

I thought my .gitignore files were fine. Most of us probably do. You drop in a template, add a couple of custom patterns and believe everything is fine. Except it often is not. Typos slip in. Old entries linger. Some lines silently match nothing at all. Others match far more than you expect. I only realised this when I accidentally uploaded a file that should never have been in the repo. Unpicking it from multiple commits was a nightmare and it sent me down a rabbit hole. To understand what was going on, I needed a quick way to see which patterns were actually matching something in my workspace. The real numbers. Which is how IgnoreLens was born. IgnoreLens gives you a live insight into your .ignore files. It shows: how many files each ignore line matches which patterns match zero files places where you may have typos or dead entries It simply shines a light on the reality of your ignore rules so you can tidy them up with confidence.

Introduction: Why Your VPN Stops Working In the era of total network control and DPI (Deep Packet Inspection), standard solutions for ensuring availability (like OpenVPN or classic Shadowsocks) are quickly blocked. Regulators have learned to analyze traffic, even when it’s fully encrypted.

There's been a wave of articles lately about TOON (Token-Oriented Object Notation), many proclaiming it saves "50% tokens" or calling JSON "outdated" for LLM applications. I've spent some time analyzing the actual numbers. The verdict? TOON is genuinely useful—but the marketing oversimplifies reality. Let me set the record straight so you can make informed decisions about when to use it. Here's the uncomfortable truth that many TOON articles gloss over: the "50% savings" figure is typically measured against formatted JSON (with pretty-printing, indentation, and whitespace). But real-world API calls and LLM prompts use minified JSON. When you compare against minified JSON - which is what you're actually sending to your LLM—the picture changes dramatically: Data Type vs Minified JSON Real…  ( 9 min )

WebSockets provide a powerful way to enable real-time, bidirectional communication between clients and servers.

The Multi-Account Reality Check In modern cloud architecture, multi-account strategies are the norm. We separate development from production, and often centralized shared services into their own hubs. A very common scenario is having a central "Security" or "Shared Services" AWS account holding sensitive database credentials in AWS Secrets Manager, which need to be accessed by a Lambda function running in a completely different "Workload" account. It sounds simple on paper: Create the Secret in Account A. Attach a resource policy to the secret allowing Account B to read it. Give the Lambda in Account B IAM permission to read the secret. You deploy your Terraform, invoke your Lambda, and... fail. You get an AccessDeniedException or a vague KMS error. I recently ran into this exact wall. H…  ( 8 min )

Anthropic just acquired Bun. First acquisition ever for the company behind Claude and Claude Code. Most takes I've seen focus on speed. "Claude Code needs fast tooling."

There’s a pattern I keep seeing in the developer world today: many people begin their journey by jumping straight into JavaScript frameworks. I’ll be honest — I made this mistake myself. When I first started coding, I jumped straight into JavaScript frameworks without really understanding the fundamentals of the web.

Java's expm1() Method: The Hidden Gem for Flawless Exponential Math (No, Really!) Alright, let's talk about something in Java that sounds like boring math but is actually a low-key superhero for writing correct and precise code. We're diving into Math.expm1(). If you're like most devs, you've used Math.exp(x) a bunch. Need e^x? Cool, Math.exp(x), done. But what about when you need e^x - 1? Your brain instantly goes, "Easy, Math.exp(x) - 1." I get it. It seems logical. But here's the kicker: for tiny values of x, that simple subtraction can be a silent data assassin. That's where Math.expm1(x) swoops in. It's not just a niche function; it's a fundamental tool for writing robust numerical software. Let's break down why, without the jargon overload.

In her recent interview, Julia Kasper, co-founder and CEO of Zukunftmoor, argues that rewetting drained peatlands represents the single biggest climate opportunity in agriculture today. Although peatlands cover only about 3 % of the global land surface, they store more carbon than all the world’s forests combined. When peatlands are drained, a common practice for agriculture, they don’t just release CO₂ once; they leak carbon continuously, year after year. Restoring peatlands thus stops that “constant leak,” and rewetting them can turn a major source of emissions into a long-term carbon sink. But rewetting alone is not enough: farmers need viable, sustainable livelihoods. That’s where Zukunftmoor’s innovative approach comes in. They propose combining rewetting with cultivation of Sphagnum moss — a natural plant of peatlands — which can serve as a sustainable substitute for extracted peat in horticultural substrates. This turns rewetting from a purely ecological restoration act into a market-driven, economically viable land-use model. By using drones or hand-seeding methods, and developing harvesting and substrate-supply chains, the approach offers farmers a low-input, long-term pathway to maintain income while restoring degraded peatlands. With this combination of climate mitigation and practical agriculture, Kasper’s vision offers peatland regions across Europe a concrete alternative to drainage-based farming — one that aligns environmental restoration with economic viability.

Introduction Microsoft Excel remains one of the most enduring and significant tools in the world of data analysis. Before the rise of sophisticated analytics platforms and business intelligence software, Excel was the starting point for many firms to investigate data-driven decision-making. As a spreadsheet tool, Excel helps users to organize, modify, and visualize data in ways that make patterns clearer and insights easier to discover. In contrast, business intelligence (BI) refers to the methods, tools, practices, and technology that transform raw data into meaningful information that is useful for making operational and strategic decisions. While BI has evolved, Excel continues to play a crucial role in bridging the gap between simple analysis and complex enterprise-level insights. Ex…  ( 8 min )

Java has evolved dramatically since the days of verbose anonymous classes. With Java 8, the language embraced functional programming through lambda expressions—and today, they're foundational: Streams, concurrency, collections, event handling, and reactive systems all depend on them. If you're a working engineer who wants cleaner, more maintainable Java code, mastering lambdas isn't optional—it's essential. Let's break down lambda expressions with real-world examples you can use immediately. A lambda expression is a concise way to implement a functional interface—an interface with exactly one abstract method. Before lambdas: Runnable r = new Runnable() { @Override public void run() { System.out.println("Hello from thread!"); } }; With lambdas: Runnable r = () -> System…  ( 9 min )

MDX Content: # Achieving Fast Response Times with Laravel and Nginx Achieving very fast response times with a Laravel app behind Nginx is mostly about avoiding bootstrapping PHP/Laravel on every request. You can accomplish this with: A 300 ms TTFB (time to first byte) for a small site with about 50 records is often caused by: Even with small datasets, the cost of spinning up the framework on every request is high compared to serving a static or cached response directly from Nginx. Nginx FastCGI cache is the key to implementing full-page caching in front of Laravel. It allows you to store the final HTML response on disk (or in memory) and serve it directly, bypassing PHP on subsequent requests. Conceptually, you need to: A typical configuration includes fastcgi_cache_path to define the cach…  ( 9 min )

(This article only discusses content safety for text generation, not multimodal.) Connecting AI inputs/outputs to a content‑safety filtering system is almost a must‑have feature for any AI gateway. For compliance, on the one hand, personal information in the context needs to be desensitized; on the other hand, certain inappropriate statements need to be sanitized. Most content‑safety filtering systems on the market work similarly: they take a piece of text and return processing results (whether to filter, which rules were violated, what text needs to be replaced, etc.). In fact, an AI gateway can have a dedicated content‑safety subsystem placed on the proxy path. Different content‑safety vendors are just different providers for this subsystem; only the integration formats and configs diffe…  ( 9 min )

I recently tried to implement a secure OTP-based email verification and password reset flow - only to realize how little concrete, end-to-end guidance is out there. Most write-ups simply skip the gritty parts because everyone seems to rely on external auth providers. I wanted something I could fully control, so I built a self-hosted solution from scratch while thinking carefully about OTP generation, hashing, crypto, race conditions and a smooth user experience. ⚠️ Disclaimer: These are just my personal notes and reflections, not exhaustive security guidance. Evaluate and adapt them to your own system requirements. Prevent email enumeration by making sure all requests take constant time. This can be implemented as a middleware that “sleeps” if a request takes less than a certain amount of …  ( 10 min )

A version of this article originally appeared in my personal blog on November 4, 2025 If you're working in a project that is in active development, it's very likely you perform many repetitive tasks that you have done before and will inevitably need to do again in the future. For instance, perhaps you often need to add functionality to your application that calls a given REST API, deserializes its JSON response into a DTO (Data Transfer Object), and then transforms it into a domain object that your app can consume. While the exact endpoint, data payload, and purpose may change from one instance to another, the actual steps in the implementation often remain largely the same. This type of process—fetching data, parsing it, and integrating it into your domain model—is so common in software d…  ( 10 min )

Central banks don't usually sound alarms about specific technologies. When they do, it's worth paying attention. This week, the Bank of England warned that a multi-trillion dollar spending boom in artificial intelligence infrastructure financed by debt risks unraveling given "materially stretched" stock market valuations. The Bank of England projects that approximately $5 trillion will be spent globally on AI infrastructure over the coming five years. Initially, Big Tech funded this build-out from their massive cash reserves. But that's changing fast. The Bank now estimates that nearly half of the $5 trillion expected to be poured into AI infrastructure over the next five years will come from external financing, particularly through debt markets. That shift matters enormously. When compa…  ( 8 min )

Three nations. One crown. $205 billion at stake. Welcome to Africa's most fascinating economic rivalry where the future of finance is being written not in Silicon Valley, but in Lagos, Johannesburg, and Nairobi. While Wall Street debates whether crypto is the future or a fad, three African nations have already moved past the conversation. They're not asking IF cryptocurrency matters, they're fighting over WHO will dominate it. South Africa, the sophisticated first mover with institutional muscle and regulatory maturity. Nigeria, the scrappy volume king with grassroots adoption that shocks the world. Kenya, the strategic latecomer positioning itself as the "gateway to Africa" with fresh regulation and tech savvy ambition. Between July 2024 and June 2025, Sub Saharan Africa processed over $2…  ( 17 min )

Hey there, Dev.to Community! 👋 Are you looking to boost the performance of your 3D scenes with a large number of MeshInstance3D or procedural geometry? Look no further than the Merging Meshes add-on for Godot 4! Merging Meshes is a simple but powerful add-on designed to optimize your scenes by combining multiple MeshInstance3D nodes into a single mesh. This reduces the number of drawing calls, resulting in a significant performance boost. Merging Meshes uses the SurfaceTool class to append meshes from MeshInstance3D nodes. This allows you to combine an unlimited number of meshes into one, drastically improving performance. Download and enable the addon: Make sure the folder is located in the addons directory. Add a MergingMeshes node: Add the MergingMeshes node into your scene. Configure the node: In the Inspector panel, add your MeshInstance3D nodes to the meshes parameter. Optional: Assign a Material3D to the GeneralMaterial parameter to set the material for the merged mesh. Recommended: Keep the HideSource parameter enabled to automatically hide the original MeshInstance3D nodes. Download on Github. This mini-add-on is part of a larger project I'm working on for Godot 4. Stay tuned for more updates and features! If you found Merging Meshes helpful, consider starring the repository to make it easier for others to find it. Happy coding! 🚀  ( 6 min )

Today, whatever is new quickly becomes old. We started with AI, then moved to Generative AI, and now it's Agentic AI. Honestly, the lines blur because everything overlaps and shines depending on our use cases and requirements. Before diving deeper, it's also key to clarify the difference between Generative AI and Agentic AI. Generative AI is reactive; it creates content, text, images, and code based on user prompts. It focuses on what to create when asked. In contrast, Agentic AI is proactive and autonomous. It takes initiative, sets goals, plans multi-step workflows, makes decisions, adapts dynamically, and executes tasks with minimum supervision. Generative AI powers content within these systems, but Agentic AI orchestrates entire processes to achieve goals efficiently, turning AI from a…  ( 8 min )

Derek Mobley thought he was losing his mind. A 40-something African American IT professional with anxiety and depression, he'd applied to over 100 jobs in 2023, each time watching his carefully crafted applications disappear into digital black holes. No interviews. No callbacks. Just algorithmic silence. What Mobley didn't know was that he wasn't being rejected by human hiring managers—he was being systematically filtered out by Workday's AI screening tools, invisible gatekeepers that had learned to perpetuate the very biases they were supposedly designed to eliminate. Mobley's story became a landmark case when he filed suit in February 2023 (later amended in 2024), taking the unprecedented step of suing Workday directly—not the companies using their software—arguing that the HR giant's al…  ( 18 min )

I built an Open Source Instagram Unfollowers tool (No Login required) 🛡️ Hi everyone! 👋 I was tired of "Unfollowers" apps that require a monthly subscription, show tons of ads, or worse—ask for my Instagram password (which is a huge security risk). So, being a developer, I decided to build a safe, open-source alternative. I took inspiration from existing community scripts and wrapped them into a modern, user-friendly tool with a brand new Glassmorphism UI and Mobile support. It's a script that runs locally in your browser console. It scans your followers/following lists using your active session and shows you exactly who isn't following you back. 🛡️ 100% Safe: It runs on your side (client-side). No password required. ⚡ No Login: It uses your active browser session cookies securely. 📱…  ( 7 min )

Python is currently the best tool for training machine learning models (AI), with many tools available in the Python ecosystem - like PyTorch and Hugging Face Transformers - it has never been easier to create a proof of concept for an AI model. We are big fans of Python because of how easy and flexible it is. However, let's take a look at the deployment aspect of using the model. When it comes to inference (running a trained model) on platforms where you need to run a model in a production environment or on a device that is not a computer, Python starts to show its disadvantages. If you've tried deploying a PyTorch application before, then you already know the pain points involved in the process. You have to create a multi-gigabyte Docker container image just to run a simple Python script.…  ( 9 min )

WebAssembly (WASM) is rapidly evolving into the “universal virtual machine”. Originally designed to let browsers run non‑JavaScript code, WASM has grown beyond its initial scope. Today, major toolchains such as C/C++, Rust, Go, Zig, and even higher‑level languages like Python and C# can compile to WASM, making it a powerful cross‑platform runtime. Both the WASM Virtual Machine and the Java Virtual Machine (JVM) are stack‑based machines. This architectural similarity means that compiling from WASM bytecode to JVM bytecode is not only possible but practical. Projects like Chicory demonstrate this by translating WASM modules into native JVM classes. This approach solves a long‑standing problem: How do we reuse existing C/C++ libraries in modern toolchains without rewriting everything? Tradi…  ( 7 min )

Hello there!👋🧔‍♂️ Today, we're exploring the three main service lifetimes: singleton, scoped, and transient. Understanding dependency injection (DI) lifecycle management is crucial for building reliable applications. Get it wrong, and you might end up with memory leaks or shared state bugs. Get it right, and your code will be cleaner and easier to maintain! When you register a service in a dependency injection container, you need to specify its *lifetime, how long the container should keep an instance alive. The three main lifetimes are: Singleton - One instance for the entire application lifetime Scoped - One instance per scope (typically per HTTP request in web apps) Transient - A new instance every time it's requested Singleton is like having one shared tool that everyone uses. There'…  ( 10 min )

CSS: if you’re afraid of deleting CSS, your code is legacy. The standard is deletability (Tailwind / zero-runtime CSS-in-JS). JavaScript: mutating objects causes most “weird” bugs. Use immutability by default. React: stop using useEffect to calculate totals. Use derived state during render. Career: companies don’t pay for “beautiful code”. They pay for performance and profit. Let’s be brutally honest: your job title on LinkedIn won't protect you from the next round of layoffs. This is not just another rant; this is a 2025 Frontend Career Guide for those who want to survive. If your routine is still waiting for a Figma file to "translate" pixels into React and installing five libraries just to build a form, you have a target on your back. The bubble has burst.

When using Scrapy for large-scale, high-frequency data scraping, simple proxy settings are no longer sufficient. Random IP rotation and fixed delays can lead to inefficiency, IP waste, and even trigger more sophisticated anti-bot mechanisms. Deeply integrating residential proxies with Scrapy and performing performance tuning is an essential skill for building industrial-grade, robust, and efficient data pipelines. This article goes beyond basic proxy middleware configuration, delving into how to implement intelligent IP management, dynamic performance optimization, and cost control within the Scrapy framework to unlock the full potential of residential proxies. The traditional proxy integration method (setting a single proxy in settings.py) is fragile. We need a more robust architecture. R…  ( 10 min )

This article is for anyone writing Playwright tests with AI assistance TL;DR: AI agents using Playwright MCP often write positional selectors like getByRole('button', { name: 'Add to Cart' }).nth(8) or chain parent traversals like locator('..').locator('..') because accessibility snapshots omit non-semantic containers. Verdex is an experimental MCP Server that solves this through progressive disclosure at two layers: Layer 1 - Three DOM exploration primitives (resolve_container, inspect_pattern, extract_anchors) reveal structural information incrementally, using ~3k tokens per exploration instead of 50k+ token DOM dumps. Layer 2 - AI assistant configuration (cursor rules, Claude skills, or similar) teaches LLMs how to compose these tools correctly, loading instructions progressively. Toget…  ( 33 min )

Hello everyone, I'm excited to share two Python libraries I've been working on recently: llmlog_engine and mini_faiss. Both tackle performance-critical problems in production AI systems with C++ implementations under the hood while providing clean, Pythonic APIs. For context, I've been building LLM-powered applications in production, and two recurring bottlenecks kept appearing. First, analyzing application logs to understand model behavior, error rates, and latency patterns was painfully slow with pandas alone. Second, running similarity searches on embeddings for retrieval systems felt like overkill with full FAISS for smaller datasets, yet pure NumPy was too slow. I explored existing solutions but found a gap: llmlog_engine addresses the need for a lightweight, embedded analytics engine…  ( 10 min )

Let’s be real for a second. Insurance apps are full of repetitive, predictable flows: Do we really want to rebuild the same steps every single time? Guidewire took one look at that chaos and said: “Developers deserve better. And faster. And less repetitive stress.” That’s why Patterns exist in JDP (Jutro Digital Platform). If Jutro Components are the LEGO bricks, Patterns are the pre-built LEGO sets that already look like a car, a house, or a spaceship, you just customize the colors and stickers. In simple words: Patterns are reusable, ready-to-go UI flows built from multiple Jutro components, designed specifically for insurance journeys. You don’t have to reinvent multi-step forms, document upload flows, payment steps, quote summaries, or review pages. Patterns say: It’s like having a fri…  ( 7 min )

I spent two months building a feature that I deleted in a single afternoon. The code was clean. The tests passed. The architecture was solid. But the fundamental approach was wrong, and no amount of refactoring could save it. I had optimized for the wrong metric, built for the wrong use case, and designed around assumptions that reality brutally disproved. Two months of work. Gone. My first instinct was to bury it. Pretend it never happened. Move on to the next thing and hope nobody asked too many questions about that mysterious gap in my commit history. After all, why would I want to document my failure publicly? Then I wrote a post-mortem. Not for my team—for the internet.

Let’s be honest: we all care about bundle size. Or at least, we should. For years, bundlesize was the go-to tool for this. It was the venerated guardian of our build pipelines, ensuring we didn't accidentally ship a 5MB lodash import to production. Sadly, it has become outdated and unmaintained. I'd hoped for it to be updated, but as security checks began to scream at me for its transitive dependencies exposing all manner of issues, a replacement had to be found. As one didn't simply materialize in the ecosystem, I decided I had to build one myself. Hence, Overweight 🧳⚖️. It’s a lightweight, modern replacement for bundlesize that helps you keep your file sizes in check. It supports Gzip and Brotli compression out of the box and integrates seamlessly with your CI. The concept is simple: y…  ( 7 min )

Everyday I see a shiny new AI tool for coding: AI that writes code AI that explains code AI that reviews code AI that documents code AI that fixes bugs you didn’t even know you had Amazing. Useful. Love that for everyone. But being around developers all the time, I’ve realized something: The most exhausting parts of a developer’s job have nothing to do with writing code. We’re drowning in tools that help you code… Here are the AI tools devs actually need: 🔥 1. AI that explains a PR like a normal human Not “diff stats.” But: What changed Why it changed What broke What’s risky Who touched this last Why the code looks haunted Basically a PR therapist. 🔥 2. AI that reads Slack and gives you the real summary Because let’s be honest: 70% of Slack is noise 20% is memes 9% is confusion 1% is the thing you actually needed to know Where is the AI that says: “Here’s the ONLY thing that mattered from yesterday. You’re welcome.” 🔥 3. AI that remembers WHY someone wrote cursed code Dev: “Who wrote this?” We need an AI that reconstructs the crime scene: the context the deadline panic the hacky patch the temporary solution that became permanent the Jira ticket titled “quick fix don’t judge” This would save lives. 🔥 4. AI that tells you which meetings are safe to ignore Let’s be real: Some meetings matter. Some meetings shouldn’t exist. Some meetings actively reduce lifespan. I want AI that whispers: “Skip this one. It’s just three people arguing about naming conventions.” 🔥 5. AI for the glue work devs secretly hate The real energy traps: clarifying requirements translating vague messages remembering decisions tracking discussions chasing answers updating docs keeping everyone aligned context-switching 47 times a day This is the work no AI tool touches… AI for glue work will be bigger than AI for code. 💬 Your turn I want to know from actual devs: What’s ONE AI tool you wish existed — not for coding, but for your sanity?

You know the feeling. You spend three hours on a Saturday night with Claude or Cursor. You’re in the flow. You prompt, it generates, you paste. The app works. You show your non-technical friends who think you’re a genius, and you feel like you’ve unlocked a superpower. Life is good. Then, the hangover hits. You notice a bug, or you want to add a "quick" feature. Or worse, you pushed to production, and now users are starting to notice issues. Suddenly, you’re staring at thousands of lines of code you didn’t really write and, let’s be honest, don’t really understand.

Events are often used to decouple logic and keep a system modular. Events allow for a very modular architecture. Your system emits events at different points in time and this allows you to create a completely independent and pluggable module which hooks into these events without needing to make any changes to the core part of your system. For example, you might create a Notification module which listens to various events in your system and sends e-mail, text messages, push notifications and performs other actions related to notifying your users. All of this without ever needing to change any part of your existing codebase. Your module can have a single responsibility, be completely self-contained and independent. For example, POS systems often have a local law requiring them to implement the payment system as a completely separate module. Without events and hooks this becomes impossible. You look at the code and see that everything depends on everything, the payment system is intermingled with every other part of the system. You throw your arms up in the air and say, no way, this can't be done. Payments are the very core of a POS system. It runs through everything. But that is just a sign of a badly architected system. It doesn't need to be this way. Everything should not depend on everything. That's a brittle system. With an event-driven, modular architecture you simply emit events and let the payment module hook into these events and handle the logic. Think of a radio broadcast (emitting events). The broadcaster simply broadcasts into the air. Anyone who wants to and has a radio (listener) tuned to the frequency hears the message. The broadcaster doesn’t know or care who’s listening.  ( 6 min )

Have you noticed how our world is built on abstractions? Abstractions are everywhere. We have abstractions in code - one library depends on another library which depends on another and so on. But it's not just code. We use abstractions every day. Every time you plug something into a wall outlet - you are using an abstraction, a huge electrical infrastructure with its own abstractions, completely invisible and hidden from you. When you drive your car, you don't operate with gears and wires, instead you turn a key, push a button, turn the steering wheel. You don't care how it works - you don't even want to know how it works. You're using abstractions to get where you need to go. Imagine a world without abstractions.

Debugging a Django application running inside a Docker container can feel like trying to fix a car engine while it's still running—challenging, but definitely not impossible. If you've ever found yourself staring at cryptic error messages with no stack trace, or wondering why your breakpoints never trigger, you're not alone. This guide will equip you with the tools and techniques to effectively debug Dockerized Django applications. Docker containers are designed to be isolated, lightweight, and production-like. While this is great for deployment, it creates some unique challenges for debugging: Limited direct access to the running process Logs can be scattered or hard to follow Interactive debuggers require special configuration File system isolation makes it harder to inspect state Networ…  ( 15 min )

A lot of junior developers misunderstand DRY (Don't Repeat Yourself) as a strict rule against any code duplication. To them DRY means: never repeat a line of code never have two components share similar structure never write anything twice If something looks similar, they feel obligated to merge it, abstract it, or build a “super component” with flags and conditions. Of course, the result is always the same: Overcomplicated, brittle, unreadable code that was technically DRY — and practically unusable.. Imagine if a cookbook tried to follow the the DRY principle to the extreme. Instead of having separate recipes for different types of pizza, it would try to create one giant single pizza recipe that covers every possible variation - one "single universal pizza recipe". “Use tomato sauce unle…  ( 7 min )

When working on a shared GitHub repository, your workflow can either make collaboration smoothor create endless conflicts, broken code, and frustration. Many developers struggle with one common question: “Should I pull changes before starting new work, or should I code first and pull later?” The truth is: The most efficient and professional workflow always begins with pulling the latest changes before you start. This article breaks down the ideal Git workflow used by teams in top engineering organizations. 1. Always Start by Pulling the Latest Changes Before you write a single line of code, ensure your local environment is up to date. Pulling first guarantees: You’re working with the latest version of the project You avoid rewriting features that someone already updated You minimize merg…  ( 8 min )

Most MCP (Model Context Protocol) tutorials show you how to build local servers that connect to Claude Desktop via stdio. That's great for development, but what if you want your MCP server accessible from anywhere? What if you want it running on the edge with sub-50ms latency globally? I built an MCP server on Cloudflare Workers that provides semantic search using Vectorize and Workers AI. Along the way, I discovered the MCP SDK wasn't designed for serverless environments - so I had to adapt it. In this article, I'll show you: Why MCP on Workers is powerful (and tricky) Three different MCP architectures I built How to adapt the stdio-based SDK for HTTP A working semantic search implementation with Vectorize When to use each architecture By the end, you'll have the knowledge to deploy produ…  ( 13 min )

Sega’s Dreamcast was known for pushing boundaries and innovation. Among its most ambitious experiments was Seaman, a virtual pet / life-simulation that combined evolution, real-time care, and voice interaction. Long before ChatGPT and LLM-powered agents existed, Seaman gave us something similar in spirit: a creature that listened, remembered, responded, and evolved based on your interaction. The game used a microphone accessory plugged into the Dreamcast controller to let players speak to Seaman. The underlying voice-recognition engine was limited and supported only a vocabulary of around 100 words or short phrases. Rather than full natural-language parsing, Seaman used a navigation-style conversation model: the game anticipated likely user inputs from a predefined set of options, and ma…  ( 8 min )

Localization in Flutter sounds simple on paper: “Just use ARB files, run the generator, and you’re done.” Right? Right… until your app grows to hundreds of keys, multiple languages, different plural forms, nested folders, and a team of devs all touching the same translations. I’ve been there. Localization is one of the most annoying parts of Flutter development. Even with tools like easy_localization helping us generate code and structure files, there are still several pain points that never went away for me. So I built a tool to fix them — but let me start with the problems first. JSON files are fine when you have: title: “Hello” button_ok: “OK” button_cancel: “Cancel” But with real apps, things turn into this: settings.notifications.push_title settings.notifications.push_body profile.fo…  ( 12 min )

Sometimes, fixing a GPU on Linux feels less like tech work and more like a mystical quest. That was exactly my journey with an NVIDIA GTX 1050 on Ubuntu 24.04 LTS. Xorg kept crashing. Logs screamed about missing modules. The system would randomly freeze, then reboot. Despite having NVIDIA 535 installed earlier, only one monitor worked under the fallback modesetting driver. Nouveau was blacklisted, yet the GPU refused to fully awaken. Purged all nvidia-* drivers, blacklists removed. Verified that nouveau was not loaded. Kernel headers were up to date. Success? ✅ Partial. The system booted with modesetting, but Xorg was still using VESA, single monitor only, GPU idle. Installed NVIDIA 535 via apt, purged, reinstalled, repeat. Every time, nvidia-smi reported the driver version, kernel modules…  ( 7 min )

As developers, we all want clean, consistent code. Tools like pre-commit make this possible by automatically running linters, formatters, and other checks before a commit. However, if you’ve used them in a real project, you’ve probably encountered the dreaded commit-hook loop. I recently faced this issue while working on a Django project. Let me walk you through the problem and how I fixed it. I’m building a Django project with a typical Python stack: Django 5.x Python 3.12 Black for formatting Flake8 for linting isort for import sorting pre-commit for managing all hooks The goal is simple: enforce code quality automatically on every commit. Here’s the workflow I was using: git add . git commit -m "Some message" At this point, pre-commit hooks run automatically. If a hook fails (say Black …  ( 7 min )

Have you ever wondered what the little padlock 🔒 next to a website’s address actually means? Or why some URLs start with https:// instead of http://? Let’s break it down—no jargon, just clarity. The Problem with Plain HTTP HTTP (Hypertext Transfer Protocol) is the original way browsers talk to websites. But here’s the catch: it’s like sending a postcard through the mail. Anyone handling that postcard—your internet provider, a hacker on the same Wi-Fi, or even someone snooping on network traffic—can read everything on it. If you log in or enter your credit card on an http:// site? That data travels as plain text. Yikes. 💡 Think: Would you write your password on a postcard and drop it in a public mailbox? Probably not. Enter HTTPS: Your Digital Envelope HTTPS (HTTP Secure) fixes this by ad…  ( 7 min )

Look, we need to talk about async testing in Python. If you've ever stared at a ModuleNotFoundError: No module named 'trio' when you're just trying to test your FastAPI endpoints, you know the pain. You didn't ask for trio. You don't even know what trio is. You just want your tests to pass. Let's fix this properly. Here's the thing about async Python: your async/await code needs an event loop to run. That's not optional. And there are multiple event loop implementations out there: asyncio - Python's built-in standard library solution trio - Third-party library with structured concurrency curio - Another third-party option (less common these days) When you're testing async code with pytest, you need something to manage these event loops. Enter pytest-anyio - a plugin that's supposed to make…  ( 10 min )

Angular has taken a big leap forward with the introduction of Signals, a simpler and more intuitive reactivity model designed to solve long-standing challenges with change detection, manual subscriptions, and complex RxJS patterns. If you’re looking to write cleaner and more predictable Angular code, Signals are the game-changer you’ve been waiting for. What Are Signals? A signal is a special reactive variable. When its value changes, Angular automatically updates the UI — no subscriptions, no async pipes, no boilerplate. `import { signal } from '@angular/core'; const counter = signal(0); counter(); // returns 0 Think of a signal as a state container that “reacts” when changed. Why Should You Use Signals? No more manual subscriptions No subscribe() or unsubscribe() headaches. Predictable UI updates Only affected parts re-render. Cleaner component logic You read a signal like a function: mySignal(). Perfect for local and shared state Simplifies component state management dramatically. How to Use Signals in Angular Create a Signal count = signal(0); Read It in the Template Count: {{ count() }} ${this.firstName()} ${this.lastName()}); Whenever firstName or lastName changes, fullName updates instantly. Effects — Run Logic When Signals Change effect(() => { Perfect for API calls, logging, or reacting to state changes. Scenario Signals RxJS Signals are not replacing RxJS — they are simplifying many common cases where RxJS felt too complex. Angular Signals bring a modern, lightweight, and highly predictable reactivity model to Angular. Whether you're building small features or large applications, Signals help you write cleaner code with less mental overhead. If you haven’t tried Signals yet, now is the perfect time — your Angular workflow will feel faster, simpler, and more enjoyable.  ( 7 min )

A Deep, Extended, Example-Packed Article Managing memory properly in JavaScript is one of the most critical skills for building fast, stable, and scalable applications. Whether you're developing a complex frontend interface, a long-running SPA, a Node.js backend, or a real-time system, poor memory handling can cause slowdowns, UI freezes, increased RAM usage, or even total crashes. JavaScript has automatic memory management through its garbage collector, but automatic does NOT mean perfect. Incorrect coding patterns will easily prevent the garbage collector from doing its job — resulting in memory leaks and wasted resources. This article is a full deep dive, expanded far beyond the standard explanations, with plenty of examples, patterns, anti-patterns, best practices, and developer tests …  ( 10 min )

Last week, I asked Claude to create a memory leak in Swift's Task API, for an amusement purposes. It gave me code and claimed the Task captures self strongly, creating a retain cycle. It suggested using [weak self]. I knew something was off. Tasks don't create retain cycles by default, that's literally their design advantage. I diasgreed with him and he started to explain why I am right. The problem is that other than trusting his words I did not have any other way to prove I am right. It turns out the Swift compiler creates something called SIL (Swift Intermediate Language) - an intermediate representation that shows exactly what the compiler does with your code before turning it into machine code. It's like looking at the compiler's notes. bash %14 = function_ref @(extension in Swi…  ( 7 min )

Watch this on YouTube: DevFest Vienna 2025 Online Navigation Online navigation works quite similarly to offline navigation, only the tools differ greatly. For online navigation, we mainly have zoom, screen magnifiers, and screen readers (or SR for short). Zoom and screen magnifiers are pretty easy to wrap your head around, either because you tested it on purpose or accidentally hit Ctrl while trying to scroll and got a jump scare by gigantic UI elements: They make things big. Checks out. But screen readers are more intimidating at first. You boot them up and suddenly everything starts talking!

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. The core functionality relies on a single multimodal API call. The key prompt I crafted was designed to leverage both image and text inputs: "Analyze the image’s aesthetic and colors, then generate a detailed 3D doodle-style creature sticker that reflects '[User’s Personality Notes]' and matches the image’s style." I utilized the Studio's multimodal capabilities and the Prompt Engineering interface to rapidly iterate on the visual style and consistency. Here is a quick look at the user experience, from input to output: Input: The user shares a photo and simple text notes. Output: The generated, custom DoodleMate. Working through the Google AI Studio track offered several key takeaways and surprises: 💡 What I Learned Prompt as Code: The process truly felt like "prompt engineering." Tweaking words like "3D sticker," "whimsical," or "charming" acted like visual parameters, allowing me to refine the product's aesthetic without touching any traditional code. 🤯 What Was Surprising If you're looking for a quick, creative project, using Google AI Studio for multimodal tasks is the perfect way to turn pixels into personality!  ( 7 min )

I remember when Blazor was the weird kid at the .NET party. "You want to run C# in the browser? That's adorable." Fast forward to 2025, and Blazor in .NET 10 is no longer the underdog—it's a genuine contender. Blazor has always worked. But some patterns required more ceremony than they should. .NET 10 finally streamlines the rough edges. Here's what many developers experienced. You start a Blazor project. You're excited. You write components. They work. Life is good. Then your boss says: "Why does the page flash white during navigation?" And you discover prerendering. And hydration. And the double-render problem. The framework handled all of this—but you had to write the wiring yourself. Serializing state manually, juggling OnInitializedAsync vs OnAfterRenderAsync, building abstractions th…  ( 14 min )

In today’s digital world, businesses are constantly looking for smarter ways to reach the right audience. For a long time, improving visibility online meant working on SEO (Search Engine Optimization). But now, there’s another approach becoming increasingly relevant — GEO (Geographic Engine Optimisation). If you’ve encountered “GEO” somewhere and wondered what it means — and how it differs from SEO — this guide aims to clarify both concepts simply. What Is GEO? GEO is a marketing approach that optimizes a website’s content for specific geographic locations rather than a broad, global audience. Instead of generic content targeting high-volume global keywords, GEO customizes offerings to people in particular cities, states, or regions. In short: SEO helps your website rank for a keyword, glo…  ( 8 min )

The Problem with Productivity Apps When my semester wrapped up, I knew exactly what came next: a focused stretch of interview prep and personal learning. I wanted to set clear goals and track my progress properly, not in a vague “I think I did something today” way but with real structure and accountability. Naturally, I turned to productivity and habit-tracking apps. Too Slow: Switching contexts to a separate app and clicking through menus just to log a task felt cumbersome and killed my flow. Too Distracting: Notifications, overly complex UIs, and features I didn't need turned "checking a box" into a time-sink.

Barefoot shoes are a modern type of footwear designed to give the feeling of walking barefoot while still protecting your feet from the ground. Unlike traditional shoes with thick soles and heavy cushioning, barefoot shoes are thin, flexible, and shaped like the natural human foot.

Key Features of Barefoot Shoes Zero Drop Sole The sole is flat from heel to toe. There is no raised heel. This encourages natural walking posture and reduces pressure on knees and back.

In this article I try to explain how hashing, encryption, and encoding work in real cybersecurity systems. ✅ 1. Encoding: Format Change Only Encoding only changes data format.

Performance of web applications is critical for several reasons. The first thing it does is change how users feel. User frustration and eventual product abandonment can result from pages and apps that take too long to load. Search engines also heavily consider how fast a website loads. Particularly, Google has acknowledged that page load times are considered by all of its product ranking algorithms. Conversion rates and income can both benefit from faster page loads. Users have high expectations when they visit your website. They might not be very understanding if the site takes a while to respond. People prefer websites that take less than two seconds to load. If there's any kind of delay beyond this point, the user is likely to leave the site, which will dramatically increase your bounce…  ( 11 min )

Large Language Models (LLMs) have become incredibly powerful at generating fluent, human-like text. But they come with a major flaw: In this post, we’ll understand why hallucinations happen and explore practical reasoning-based techniques to reduce them. Hallucination isn't a bug — it's a natural consequence of how LLMs work. LLMs are trained to predict the next token, not to verify facts. If the model has never seen a particular fact or topic clearly in training data, it will guess based on patterns. Rare topics Very new information Domain-specific technical questions If a prompt presupposes a false fact, the model tends to follow the user’s framing. A naïve model will try to answer instead of correcting you. LLMs don’t have a database or knowledge graph by default. How to Reduce Hallucin…  ( 8 min )

React is a great tool for making user interfaces because it is modular, can be used again and again, and renders quickly with the virtual DOM. But there are unique difficulties to be aware of when dealing with React. Complex issues such as scalability, productivity tuning, and state management require a combination of technical knowledge and analytical thinking on the part of developers. Here we'll take a look at the most common challenges encountered by React developers and provide some practical solutions on how to fix them. Managing different kinds of data and state is a common requirement for React applications. Efficiently managing state across components can become more challenging as your application grows. Sharing and syncing state across numerous components can cause confusion and…  ( 13 min )

For the Kiroween Hackathon 2025, our mission was simple: blend the ultra-minimalist, nostalgic aesthetic of the late '90s web with a powerful, real-time network engine. The result is NetSpeak, a fully functional, ugly-chic chat application. It might look like it runs on a 56k modem, but under the hood, it's blazing fast. The Stack: Old Look, New Muscle We kept the frontend deliberately bare-bones (vanilla HTML, CSS, JS) to nail that retro vibe. However, the communication layer is all modern efficiency: Backend: Node.js / Express.js Real-time: Socket.IO Aesthetic: Pure, unadulterated, intentionally bad CSS. The contrast is the core feature: incredibly low-latency performance hidden behind a deliberate commitment to nostalgia. The Secret Weapon: Kiro AI Frankly, we couldn't have finished NetSpeak in time without Kiro, our AI-powered IDE. Kiro's lightweight design and streamlined UI/UX were game-changers. The AI Autopilot feature was particularly invaluable. It took over the scaffolding of our Express server and the complex setup of our real-time Socket.IO connections. By continuously catching and correcting small syntax and logic errors, Kiro allowed us to focus purely on the core concept and design implementation, dramatically accelerating our development cycle. Conclusion NetSpeak is a testament to what's possible when you couple a minimalist vision with maximum-power AI tooling. It was a blast to build, and we're proud of the hauntingly efficient performance we achieved. Developed for the Kiroween Hackathon 2025.  ( 6 min )

Look, we all started 2025 with a beautiful spreadsheet. Color-coded tabs. Projected ROI that would make a CFO weep with joy. Maybe you even had a deck with those gradient charts that look impressive in meetings. And then reality happened. Here's the thing about marketing budgets: they're aspirational documents masquerading as financial planning. By December, that meticulously planned allocation looks about as accurate as a weather forecast from six months ago. The paid social budget got blown in Q2 when CPMs spiked. The content strategy pivoted three times. And that experimental budget for "emerging platforms"? Yeah, nobody can quite remember what that money actually bought. But December is when we get honest. Not because we're suddenly virtuous, but because Q1 2026 budget decisions are ha…  ( 13 min )

🔎 ML Observability & Monitoring — The Missing Layer in ML Systems Part 7 of The Hidden Failure Point of ML Models Series Most ML systems fail silently. Not because models are bad… Not because algorithms are wrong… But because nobody is watching what the model is actually doing in production. Observability is the most important layer of ML engineering — yet also the most neglected. This is the part that determines whether your model will survive, decay, or collapse in the real world. Traditional software monitoring checks: CPU Memory Requests Errors Latency This works for software. But ML models are different.

I originally posted this post on my blog. I'm not an AI evangelist, and I'm not a hater either. I've tried AI for coding. And after a week or two, I noticed how dependent I was becoming. Since then, I've used AI for small coding tasks, like generating small functions or finding typos, not to treat English as my main programming language. Marcus Hutchins, a security researches, puts it boldly in his post Every Reason Why I Hate AI and You Should Too: I'd make a strong argument that what you shouldn't be doing is "learning" to do everything with AI. What you should be doing is learning regular skills. Being a domain expert prompting an LLM badly is going to give you infinitely better results than a layperson with a "World’s Best Prompt Engineer" mug. I agree with the core message. When everybody is relying on AI, it's time to go back to old-school habits: Read code Write trustworthy tests Devour classic textbooks Troubleshoot bugs with pen and paper And outside coding: read books on paper, take notes by hand, and write our own summaries. To develop taste and judgment. Using AI is like holding a calculator on a math exam. Even the best calculator is useless if you don't know what to compute. Build skills, then leverage AI. I used to think coding was only about cracking symbols. That's where AI shines. But coding is also about talking to non-tech managers, negotiating deadlines, and saying no politely. And that's why I wrote, Street-Smart Coding: 30 Ways to Get Better at Coding, to share the skills I wish I'd learned to become a confident coder. Get your copy of Street-Smart Coding here. It's the roadmap I wish I had when I was starting out.  ( 7 min )

AI is transforming software engineering faster than ever, but instead of replacing human developers, it’s becoming a powerful partner. Together, humans and AI are shaping a future where development teams are more productive, creative, and impactful. The future of coding isn’t about competition—it’s about collaboration. AI tools are great at handling repetitive tasks like generating code, running tests, and spotting bugs. This frees developers to focus on the parts of the job that machines can’t handle: creative problem-solving, strategic thinking, and designing solutions that really fit business needs. Humans bring something AI can’t replicate—contextual understanding, ethical judgment, and the spark of innovation. While AI can crunch data and suggest improvements, it’s the human developer…  ( 7 min )

Building a Horror Game in 8 Hours with Kiro AI For the Kiroween 2025 hackathon, I built Layers of Static - a psychological horror experience disguised as a vintage 1970s CRT television. The twist? An AI lives inside it, asking disturbing questions and giving creepy dares. The real story isn't what I built. It's how I built it. The hackathon's "Frankenstein" category challenged us to stitch together incompatible technologies into something unexpectedly powerful. My chimera: 1970s CRT aesthetics (scanlines, phosphor glow, chromatic aberration) Modern AI (Google Gemini for conversation) Voice synthesis (ElevenLabs TTS with a little girl's voice) Web Audio API (music box loops, audio ducking, sound effects) Normally, this would take weeks.

Executive Summary The rapid integration of Large Language Models (LLMs) into production software has exposed a critical interoperability bottleneck. As developers attempt to bridge the gap between reasoning engines (like Claude 3.5 Sonnet, GPT-4o) and proprietary data sources (PostgreSQL, Slack, GitHub), the industry faces an "N×M" integration problem. Every new model requires unique connectors for every data source, resulting in fragmented, brittle ecosystems. The Model Context Protocol (MCP), introduced by Anthropic in late 2024, emerges as the "USB-C for AI," establishing a standardized, open-source specification that decouples intelligence from data. This report serves as an exhaustive technical resource designed to enable a development team to implement, deploy, and disseminate MCP …  ( 15 min )

A purely monetary view of yacht maintenance and living costs misses a critical factor: the value of your own labor. For the hands-on liveaboard, time and skill are a direct currency that can be exchanged for dramatic cost savings. Calculating this “Owner-Operator Dividend” reveals the real economic picture and highlights the skills with the highest return on investment. To quantify savings, first establish a local market rate for marine labor. In many cruising areas, skilled technician rates range from $80 to $150 per hour. This becomes your “credit rate”—the amount you save for every hour of competent work you perform yourself. Not all tasks offer equal savings. Focus on high-frequency, moderately complex jobs that have a high labor-to-parts cost ratio. Top Tier (Highest Dividend): Preve…  ( 7 min )

Rust is not the first language that comes to mind when people think about data science. Most learners start with Python or R because of their libraries and simpler learning curve. However, Rust is gaining attention due to its speed, reliability, and ability to handle large-scale computations efficiently. Developers who work on performance-heavy systems or want safer, low-level control are exploring Rust as an option. This growing interest naturally raises a question: Can Rust support data science tasks well enough to be considered a practical choice? Rust can be good for data science, but the answer depends on what you need. It is fast, memory-safe, and reliable, which makes it suitable for large datasets and production-grade systems. However, Rust’s data science ecosystem is still develop…  ( 8 min )

For years we’ve circled around the same debate: The argument is familiar. Every re:Invent, my attention usually gravitates toward new features: better serverless capabilities, smarter managed services, or breakthrough technologies that unlock new design patterns. At a high level, it looks like a straightforward agreement: improve private connectivity between the two clouds, reduce complexity, and remove some historical pain points that made multicloud networking feel like a chore. Anyone who has tried to stitch AWS ↔ Google Cloud manually knows exactly what that pain feels like. However, the implications run deeper. This partnership opens the door to a possible future where cloud systems become increasingly agnostic, where architectural decisions are driven by capabilities—not by the limitations of network plumbing between providers. Yet there’s another way to read this move: Whether this collaboration becomes a turning point in cloud interoperability or simply a convenient handshake between two giants remains to be seen. What is certain is that the market has been demanding simpler, more stable, and less painful multicloud experiences—and this announcement suggests that the providers have finally started listening.  ( 7 min )

As cloud estates grow, maintaining the integrity of Infrastructure as Code (IaC) is a critical challenge. AWS CloudFormation provides the blueprint for our infrastructure, but the reality of day-to-day operations—manual hotfixes, temporary changes, and urgent interventions—inevitably leads to configuration drift. Detecting this drift is only half the battle. The real challenge, especially when managing hundreds of stacks, is prioritizing what to fix and cutting through the noise. What if you could move beyond simple alerts and build a closed-loop system that not only detects drift but allows your team to manage, acknowledge, and prioritize it, all from within your primary communication tools?

Modern machine learning workflows rely heavily on pretrained models—downloaded from GitHub, HuggingFace, and countless other model hubs. This convenience comes with a growing risk: model tampering, data poisoning, and hidden backdoors embedded in .pth checkpoints.

The quiet shift happening in tech, and why side projects, digital products, and content creation are becoming essential—not optional. ⸻ We Are Entering a Different Era for Developers Over the last year, the tech landscape has changed faster than any of us expected. AI coding assistants are now mainstream, automation is accelerating, and companies are restructuring teams at a pace that would have been unthinkable just a few years ago. For many developers—especially those who have been in the industry for a while—this can feel unsettling. But for others, it’s a wake-up call to shift how we think about our careers. The truth is simple: pure employment is no longer the only pillar of a dev career. Developers who thrive from now on will be the ones who view themselves not just as employees, but as micro-entrepreneurs with skills that can be packaged, monetised, and scaled in multiple ways. A business mindset doesn’t mean starting a huge company or raising money. It simply means seeing your skills as assets and treating your output as something that can generate income outside your day job. Even small, steady streams of income create resilience in a world where tech layoffs can happen overnight. Here are the forces pushing developers in this direction: AI will keep accelerating (and will eventually handle more junior coding tasks) Companies are shrinking engineering teams, not growing them Career transitions now happen every 2–3 years, not 10 Apps, digital products, and online content cost almost nothing to produce One developer can now build and launch full products solo This isn’t a crisis.

The Context: An Open-Source Educational Tool I currently serve as the Tech Lead for DigitalBoneBox, an open-source educational platform designed to render high-fidelity anatomical resources for anatomy students. Our architectural constraints are unique: we needed a "database" that was completely open, version-controlled, and accessible to non-technical contributors (like anatomy professors) who might want to fix a typo or add a description without touching a database console. The solution? "GitHub-as-a-Database." We store our data (JSON files and images) in a specific data branch of our public repository. The application fetches this content via the GitHub Raw API to render the UI. While this lowered the barrier to entry for contributors, it introduced a critical engineering challenge: T…  ( 8 min )

Instant Prototypes Make It Easy to Build the Wrong Thing Quickly Just because AI lets you build fast, doesn’t mean the thing you built matters.

Unlocking Time's Secrets: Temporal Pattern Recognition for System Anomaly Detection Imagine your servers are chirping like crickets, each chirp a system event. How do you tell a normal chorus from a sign of impending doom buried within a symphony of events happening at different times and durations? Standard time-series analysis often overlooks the critical when and how long of state changes. The key is understanding the interplay between event sequence and the time spent in each state. We've been exploring a novel approach we call Selective Temporal Difference (STD). It's designed to pinpoint similarities between sequences of events, not just by the order in which they occur, but also by how long the system resides in each state. STD cleverly sidesteps the pitfall of forced time alignme…  ( 7 min )

So… I built something. A small browser extension that tells you when a website you’re visiting might be using your data to train AI models. Not in a dramatic way. And I’d love your help making it better. I’ve been following AI news for a while, and one thing keeps bothering me: our data is being used to train models, but we’re rarely told how, where, or when. Some platforms are clear about it. Artists. Writers. Photographers. Developers. After a while, I realized: There’s no easy way to check who’s training on your data. WTOM (WhoTrainedOnMe) is a browser extension for Chrome, Chromium-based browsers, and Firefox. When you visit a site, WTOM checks if that platform: Trains AI on user data It’s not perfect, but my goal is to give users clarity — not fear. How WTOM Works (A Lot of Manual Res…  ( 9 min )

🚀 The Essential Patterns Behind Modern AI Agents A Practical Guide for Developers, PMs, Analysts & Business Leaders ✅ Artificial Intelligence agents are quickly becoming the backbone of next-generation software systems. They automate decision-making, coordinate tasks, call APIs, analyze data, and even interact with users like mini-employees who work 24/7. Regardless of the framework you use (LangChain, LangGraph, CrewAI, LlamaIndex, AutoGPT…), the smartest AI agents rely on the same set of architectural patterns. ✅ Understanding these patterns is the difference between: Building a confusing chatbot, or Designing a reliable multi-agent system that solves real business problems.

O que é uma API? API significa Application Programming Interface (em português: Interface de Programação de Aplicações). Basicamente: API é um jeito de um sistema conversar com outro, trocando informações de forma organizada e seguindo regras pré-definidas. Ou seja, se um sistema quer pegar dados de outro, mandar informações, criar algo, atualizar algo… a API é quem faz essa ponte. Quando falamos de APIs como REST, elas se comunicam usando HTTP/HTTPS, o mesmo protocolo que tem no navegador. Tudo é feito através de URLs chamadas endpoints. Endpoint = endereço onde o serviço da API está disponível. : pediu → recebe algo de volta. A API responde com: dados, confirmação,ou um erro dizendo o que deu errado. E sempre vem acompanhado de um status code. 200 – OK → Deu bom. Quando você acessa um endpoint, você sempre usa um método. GET – Buscar dados POST – Enviar dados (criação de recurso) PUT – Atualizar um recurso existente PATCH – Atualizar parte de um recurso DELETE – Deletar um recurso Os formato de Dados, hoje em dia, a maioria das APIs usa JSON. { JSON é leve, fácil de ler e funciona bem com praticamente todas as linguagens. São informações adicionais que você envia na requisição. Tipo do conteúdo (JSON) Token de autenticação Idioma Permissões Sem headers, várias APIs nem deixam você acessar. Nem toda API é aberta. Muitas exigem uma maneira de provar que você tem permissão. Os mais usados: API Key Bearer Token JWT OAuth2 APIs mudam com o tempo. Por isso existe versionamento: /api/v1/clientes Exemplo Bem Simples de API com Spring Boot Você pode criar pelo Spring Initializr: https://start.spring.io/ Depois, uma API simples: @RestController Código fonte de uma api simple: https://start.spring.io/ https://www.linkedin.com/in/isaac-bessa-044a14321/  ( 7 min )

Je suis le "What's new" d'AWS de façon quasi quotidienne depuis plus de 7 ans.

If there is one thing time has taught me working in IT, it is this: getting stuck with what you already know is the fastest path to being left behind. Our field evolves constantly. You do not need to learn something new every month, but you should widen your possibilities. Learning new languages, frameworks, tools or paradigms expands your technical vision and makes you more versatile to solve real problems. It is even better when your company gives you freedom to experiment with new technologies, as long as it does not turn into chaos. Choosing technology is not about what seems cool, but about what makes sense for the context of the project. In your personal projects, explore without fear because that is where real growth happens. If I were to recommend a set of technologies today for so…  ( 8 min )

Created as part of my learning experience in the ParoCyber Ethical Hacking Program. Penetration testing is one of the most exciting areas of cybersecurity, but before any testing begins, you must have clear authorization, documented scope, and well-defined rules to protect both the tester and the client.

Understanding the checkpoint-based execution that makes long-running workflows possible You write an AWS Lambda function that looks like it runs continuously for hours. But Lambda functions can only run for 15 minutes. How does this work? The answer is replay - a checkpoint-based execution model that makes your function restart from the beginning on every invocation, but skip the work it's already done. It's elegant, efficient, and once you understand it, surprisingly intuitive. Here's the fundamental truth about durable functions: Your handler function re-executes from the beginning on every invocation, but completed operations return cached results from checkpoints instead of re-executing. Let's see this in action with a simple workflow: async function processOrder(event: any, ctx: Durab…  ( 11 min )

Introduction Dependabot automatically detects dependency updates and creates pull requests, but manually merging each one can be tedious.

Many low-code platforms are fundamentally built around a CRUD model, typically offering a certain level of customization through built-in extension points (such as before-insert, after-insert, etc.). In the Nop platform, the CRUD model is not special; the built-in CrudBizModel is merely a regular BizModel, and the core of the Nop platform does not apply any special treatment to CRUD extension points. In this article, I will use CrudBizModel as an example to explain common extension approaches for implementing backend services in the Nop platform. Most service functions in CrudBizModel adopt two layers of abstraction. The upper-layer function calls the lower-layer implementation and uses parameters and callback functions to achieve customization. public PageBean findPage(@Optional @N…  ( 14 min )

Just a few short weeks ago, Google debuted its Gemini 3 model, claiming it scored a leadership position in multiple AI benchmarks. But the challenge with vendor-provided benchmarks is that they are just that — vendor-provided. A new vendor-neutral evaluation from Prolific, however, puts Gemini 3 at the top of the leaderboard. This isn't on a set of academic benchmarks; rather, it's on a set of real-world attributes that actual users and organizations care about.  Prolific was founded by researchers at the University of Oxford. The company delivers high-quality, reliable human data to power rigorous research and ethical AI development. The company's “HUMAINE benchmark” applies this approach by using representative human sampling and blind testing to rigorously compare AI models across a va…

One problem enterprises face is getting employees to actually use the AI agents their dev teams have built.  Google, which has already shipped many AI tools through its Workspace apps, has made Google Workspace Studio generally available to give more employees access to design, manage and share AI agents, further democratizing agentic workflows. This puts Google directly in competition with Microsoft’s Copilot and undercuts some integrations that brought OpenAI’s ChatGPT into enterprise applications.  Workspace Studio is powered by Gemini 3, and while it primarily targets business teams rather than developers, it offers builders a way to offload lower-priority agent tasks.   “We’ve all lost countless hours to the daily grind: Sifting through emails, juggling calendar logistics and chasing…

Most developers spend weeks or months building something, then rush through the launch in a single afternoon. They tweet about it, post on a few forums, and then wonder why nobody shows up. The product is solid, but everything around it is an afterthought. I've done this myself. I've also watched dozens of other developers make the same mistakes. Here's what gets forgotten most often. You launch. Something breaks. A user hits the bug, gets frustrated, and leaves. You have no idea this happened because there's no error tracking, no feedback widget, nothing. You find out three weeks later when someone finally emails you. Set up error monitoring before you launch. Sentry takes maybe 20 minutes to integrate and will save you from silent failures. But error tracking only catches crashes. It doe…  ( 8 min )

The best products I’ve shipped across WordPress, Shopify, Webflow and React had one consistent pattern: clarity always beats complexity. When you strip away unnecessary layers, everything moves faster. Teams iterate with confidence, bugs drop, and the product becomes easier to scale and maintain. Simplicity isn’t about limiting ideas it’s about creating a foundation where good engineering, clean architecture, and meaningful features can actually thrive.  ( 6 min )

The last decade has pushed e-commerce, retail, and manufacturing industries into an era of rapid transformation. Customer expectations have shifted dramatically, global supply chains have become more fragile, and the pressure for speed and accuracy has never been higher. As competition intensifies and operational costs rise, businesses are realizing that traditional fulfillment methods can no longer support the pace of modern demand. This is where the idea of a future-ready fulfillment system emerges — not just as a technical upgrade, but as a new operational philosophy. Being “future-ready” no longer means simply shipping orders faster. It means building a fulfillment structure that can absorb disruptions, scale instantly, operate with data-driven clarity, and remain stable in unpredictab…  ( 8 min )

TL;DR: I built a serverless AutoML platform that trains ML models for ~$10-25/month. Upload CSV, select target column, get a trained model. No ML expertise required. To deploy this project yourself, you'll need: AWS Account with admin access AWS CLI v2 configured (aws configure) Terraform >= 1.5 Docker installed and running Node.js 18+ and pnpm (for frontend) Python 3.11+ (for local development) ⏱️ Deployment time: ~15 minutes from clone to working platform AWS SageMaker Autopilot is powerful but expensive for prototyping. While training has a free tier (50 hours/month for 2 months), the real cost comes from real-time inference endpoints: a single ml.c5.xlarge endpoint costs ~$150/month running 24/7. I needed something simpler and cheaper for side projects. Goals: Upload CSV → Get trained …  ( 9 min )

I spent 12 hours fighting a local AI model to generate valid SQL queries. My success rate went from 40% to 100%, not by prompt engineering, but by teaching the model to learn from its own mistakes.

Introduction In this tutorial, I'll walk you through how I built a semantic search engine using CocoIndex, an open-source Python library for creating powerful search experiences. If you've ever wanted to build a search feature that understands context and meaning (not just exact keyword matches), this post is for you! CocoIndex is a lightweight semantic search library that makes it easy to index and search through documents using vector embeddings. Unlike traditional keyword-based search, semantic search understands the meaning behind queries, allowing users to find relevant results even when they use different words. I needed a search solution that was: Easy to integrate - No complex setup or infrastructure required Fast - Quick indexing and search performance Semantic - Understanding c…  ( 8 min )

Day 1 at AWS re:Invent 2025 kicked off with Matt Garman’s first keynote as CEO of AWS — and the message was unmistakable: This is the AI era, and AWS is building the full stack for it. Matt structured the entire keynote around four core areas: AI Infrastructure Inference Platform Your Data Tools to Build Agents And what I loved most: after each major section, AWS brought customers on stage to share real implementations — not just theory. Sony, Adobe, and Writer all walked through how they’re building on top of these new capabilities, grounding the announcements in reality. Here’s my full breakdown. 1.

The Problem: I love Python for data analysis, but I hate writing matplotlib boilerplate just to see a simple trend. I also didn't want the overhead of a full React frontend for a simple dashboard. The Solution: I built Morph-AI-Era, a monolithic app using: FastAPI (Backend): Handles CSV parsing (Pandas) and AI Forecasting (Scikit-learn). Vanilla JS + Plotly (Frontend): Fetches JSON and renders charts instantly. Supabase: For Auth and Credits. How it works: User drags CSV. FastAPI cleans NaN values and detects date columns. Frontend renders interactive Scatter/Line charts via Plotly. Bonus: I added a "Viral PDF" generator using html2canvas. The Result: A dashboard that feels like a SPA but runs on a simple Python backend. It handles 100k+ rows in the browser without lag. Try it out: I’m looking for feedback on the forecasting logic. You can test it here (10 Free Credits for new accounts): https://www.morph-ai-era.online Let me know if you want to see the source code for the "Forecast" endpoint! python #fastapi #webdev #showdev  ( 6 min )

Introduction Atomic Design is not just a design philosophy—it’s a way of thinking about components as living organisms that grow from simple building blocks into complex, interactive systems. The Five Levels of Atomic Design Atoms: The smallest building blocks—buttons, inputs, labels, colors, and typography. Molecules: Combinations of atoms that form functional units, like a search bar (input + button). Organisms: Larger sections of the interface, such as a navigation bar or product card grid. Templates: Page-level wireframes that define layout and structure without specific content. Pages: Realized templates filled with actual data and content, representing the final user-facing product. This hierarchy mirrors nature: atoms form molecules, molecules form organisms, and organisms create living systems. Why Atomic Design Matters in Frontend Scalability: Large projects remain manageable by breaking them into reusable parts. Consistency: UI elements behave uniformly across the application. Collaboration: Designers and developers share a common vocabulary. Efficiency: Reusable atoms and molecules accelerate development. Maintainability: Changes ripple predictably through the hierarchy. Example: React Project with Atomic Design Structure Atoms: Button, Input, Typography Molecules: SearchBar, ProductCard Organisms: Header, Footer, ProductGrid Templates: HomeTemplate, ProductTemplate Pages: Actual routes like / and /product/[id] This structure ensures that every piece of UI is reusable, testable, and easy to maintain. For example, if you redesign the Button atom, the change propagates across all molecules and organisms that use it. Conclusion Atomic Design is more than a methodology—it’s a philosophy of growth, reminding us that even the most complex systems begin with the smallest building blocks.  ( 7 min )

How Semantic Search Finds Products That Keywords Miss I've been building this product search engine for Barbados called "Yuh Gettin' Tru?" (Bajan for "Are you finding what you need?"), and I wanted to share something that perfectly illustrates why semantic search matters. I was testing the site against a local home store called Dwellings. They sell all sorts of home goods - furniture, kitchenware, decor. I searched for "hardwood cutting board" on their website and got... nothing. Zero results. Now, here's the thing. They absolutely do sell hardwood cutting boards. They have these lovely acacia wood boards with handles. But their product database doesn't call them "hardwood cutting boards" - it calls them "Acacia Cutting Board with Handle". Traditional keyword search sees "hardwood" and …  ( 8 min )

TL;DR: After years of wrestling with recursive CTEs, junction tables, and the existential dread of N+1 queries, I built a graph-native Backend-as-a-Service called FLXBL. To prove it actually works (and isn't just vaporware from a sleep-deprived developer), I built a mock movie discovery platform that finds the shortest path between any two actors. Here's what I learned—and why you might want to ditch your relational database for relationship-heavy applications. Have you ever played the Six Degrees of Kevin Bacon game? The premise is beautifully simple: any actor in Hollywood can be connected to Kevin Bacon through their film appearances in six steps or fewer. Tom Hanks was in Apollo 13 with Kevin Bacon—that's one degree. Meryl Streep was in The River Wild with Kevin Bacon—also one degree.…  ( 15 min )

In the 1990s, developers wrote long functional specifications before coding. By 2010, agile replaced the idea that you should define everything upfront. Today, as AI coding struggle with quality, the old playbook is returning: writing detailed specs in hopes of getting reliable outcomes. On paper, spec-driven development (SDD) feels like the perfect solution: write a detailed spec first, then let the model generate “correct” code from it. But reality hits hard. Just like the pattern we have seen before: when we try to “solve unpredictability” by writing more things down upfront, the development fails, and always for the same reason — Reality changes faster than specs do. What Is Spec-Driven Development? Spec-driven development (SDD) is the practice of writing detailed upfront specifica…  ( 9 min )

Over the last few months I kept seeing the same problem. Teams want to move from React to Next.js but the migration is repetitive, messy, and full of hidden patterns. So I built a feature rich converter that automates most of the work: reacttonext.com. The tool handles routing changes, Link conversions, file restructuring, SSR-safe patterns, dynamic imports, and a lot of the tricky edge cases that usually show up late in a migration. I trained it on 1500 publicly available React codebases and used those patterns to build the rule engine behind it. The converter completes around 80–90 percent of the migration automatically. After that it generates a README.md containing all the remaining manual review steps. You can follow them yourself or feed the README to an LLM, since the instructions are already written in a way that an LLM can process correctly. If you want to try it or break it, here you go: https://reacttonext.com I am looking for feedback, edge cases, and real-world projects that can push its limits.  ( 6 min )

As part of my Codegeist project, I integrated this layer into a real Forge app and connected it to PostHog. Forge SQL is multitenant — the physical database is shared across many customers, and each tenant gets its own logical slice of data. In practice, this creates two major challenges: 1. Tenants can have radically different dataset sizes A resolver that runs in 50–100 ms for one customer may take hundreds of milliseconds, or even seconds, for another. And you have no way to know this ahead of time: you cannot see the tenant’s actual table sizes you cannot log into the underlying…  ( 12 min )

Hey Developers 👋 for years, Create React App (CRA) was the go-to tool for setting up React projects quickly. However, as of Feb 2025, CRA is officially sunset. The React team no longer recommends using it due to slow build times, outdated configurations, and lack of support for modern features like ES modules and native ESM-compatible dependencies. If you are still using CRA, it’s time to migrate. I have worked with a lot of teams, and in my opinion if you have a SPA application that doesn’t need the latest nuts and bolts like React Server Components, then Vite is the best option.

Most frontend projects rely heavily on REST APIs. We fetch data, handle the loading state, and display lists. While this is an essential skill, it ignores a large part of what the browser can do. I recently saw a tweet about using native Browser APIs to build more interesting projects. I wanted to try this myself, but I found it difficult to find good project ideas. Most documentation provides syntax examples but rarely explains what you can actually build with them. I created a site to solve this. It serves as a collection of browser APIs, resources, and specific project ideas for each one. You can view it here For each API, I included the MDN documentation, a couple of resources and a few project ideas. This will be updated as I find more project ideas. Focusing on these APIs requires a different approach than standard data fetching. You have to manage permissions, handle real-time events, and interact with device hardware. Asides from it being fun, it is a practical way to understand the web better. I am using this list to guide my own learning. I plan to update it as I discover more APIs and use cases. If you are looking for a new project to build, you can check out the full list here.  ( 6 min )

Crypto payments feel simple for users: scan a QR code, send funds, wait for confirmations.

A crypto payment gateway is a service (or internal component) that connects an off-chain business event—like an order or invoice—to an on-chain crypto transaction, then tells your backend when it’s safe to deliver the product. Think of it as the crypto equivalent of payment plumbing: not the blockchain itself, but the layer that makes payments usable in real apps. Popular, widely used gateways include Coinbase Commerce, RBTex, BitPay CoinGate, NO…  ( 8 min )

В данной статье мы рассмотрим несколько способов установки собственного VPN, а начнем с самого простого и доступного каждому. Для настройки личного VPN прежде всего необходимо иметь виртуальный сервер, он же VPS или VDS. Переходим на сайт VDSina (или регистрируемся здесь) и заказываем сервер с 1 процессорным ядром и 2Gb памяти. В заказе выбираем операционную систему Ubuntu 24.04 или Debian 12, и отключаем ненужную платную резервную копию: Оформив и оплатив заказ, нам сразу будут выданы данные доступа к серверу – его IP-адрес и пароль пользователя root. Теперь, когда у нас есть собственный сервер, можно переходить к непосредственной настройке VPN одним из трех способов. ㅤ Способ 1.

When Anthropic announced its acquisition of Bun, it wasn’t just a corporate move — it was a clear message: AI-native software engineering is no longer an experiment. It’s the new standard. Claude Code, Anthropic’s agentic coding system, hit $1B run-rate revenue in only six months. That type of growth has never happened in the developer tools space before. And behind that meteoric acceleration? A surprising catalyst: Bun, the JavaScript runtime created by Jarred Sumner. Today’s acquisition formalizes a relationship that has quietly shaped the fastest-growing AI coding product in history. Why Bun Matters So Much in the AI Era Bun has always been outrageous. Outrageously fast, outrageously integrated, outrageously ambitious. 7M+ monthly downloads 82k+ GitHub stars Adopted by Midjourney, Lov…  ( 8 min )

When building modern web applications, managing relationships between data entities is a common challenge. But what happens when those relationships form a dependency graph, and you need to process items in the correct order? That's exactly the problem I tackled in my latest project: a FastAPI backend that combines traditional CRUD operations with intelligent dependency ordering using topological sorting. Most CRUD APIs are straightforward—create, read, update, and delete resources. But in many real-world scenarios, resources depend on each other. Think about: Build systems where modules depend on other modules Task management where tasks have prerequisites Package managers where libraries depend on other libraries Workflow engines where steps must execute in order The challenge isn't just…  ( 9 min )

It was an honor to join Matt Stauffer on the The Business of Laravel podcast to talk about my journey: from building a startup on Laravel, to selling it, and now launching Ghostable — a zero-knowledge environment-management platform for teams that scale. If you want the full conversation, check out the episode. Here’s a written recap of what I shared, how Laravel shaped my path, and why env/secrets management matters more than most devs realize. My co-founder and I go way back — kindergarten friends, turned co-founders. Our first “company” was literally a skateboard deck brand we made in high school: hand-painted boards, a rudimentary website, and a DIY hustle. That early taste of branding, marketing, and web dev stuck. Years later, when he pitched me a security-training idea (now known…  ( 8 min )

Modern PHP applications rely on many external components: APIs, databases, file systems, random generators, time providers, and services that communicate with the outside world. This is where test doubles come into play. A test double is any stand-in object that replaces a real dependency during testing. PHP offers many ways to create these objects — manually, through libraries like Mockery, or through PHPUnit’s built-in mocking tools. In this article, you’ll learn: What mocks, stubs, spies, and fakes really are How they differ and when to use each How to build them in pure PHP How to test code that depends on external services Common mistakes developers make when mocking Simple examples you can run directly in onlinephp.io Let’s begin with the basics. There are different categories of tes…  ( 10 min )

Over the past year, I’ve been slowly moving many of the little repetitive tasks in my engineering workflow over to local LLMs. These are the tiny chores that show up dozens of times a day and quietly wear you down. Automating them away has been a real blessing. If you’re a software engineer who wants to eliminate the tedious parts and move faster, then I hope sharing some of my scripts inspires you to streamline your own workflow as well. The core of my setup is Ollama. It runs several code focused local models. You do need a little power under the hood machine to run some of these higher param models. On my M4 Mac these models have been fantastic: qwen2.5-coder:7b runs extremely fast and is more than enough for most tasks qwen2.5-coder:14b a bit slower, but best overall reasoning and cod…  ( 9 min )

"Oh man, how do these guys who are younger than me beating me at my own game?" I have been feeling this way many times of my decade long career. When I was in my formative years, I always blindly thought those and I took them as truth without thinking. And me being in my own shell made it worse. It was my third year and my manager asked me "Where do you think you rank in this appraisal cycle?". I said without any thinking "I will be within top 3" and the competition is fierce and there are 10-15 people for that appraisal cycle. My Manager smiled and I thought myself that "Who am I kidding? top 3! what a joke. He must me laughing that I am this deluded". I never asked him what he thought afterwards. But ever since he asked me that whatever work I am associated with my Manager, that thought …  ( 10 min )

Developer activity in crypto continues to rise. Although users still search for where to buy Bitcoin or check Dogecoin price charts, developers focus on networks that offer predictable performance, strong tooling, and stable infrastructure. Many consumers begin their crypto experience through platforms like MoonPay, but developers take the next step by building applications that push blockchains to their limits. This roundup covers the top networks developers are using for serious production workloads. 1. Ethereum and Its Rollups The largest developer ecosystem remains productive due to mature tools, libraries, and L2 networks that reduce costs. 2. Solana Solana offers high throughput and fast finality. Developers building consumer apps, DEXs, and real-time systems appreciate its performance profile. 3.

Community Health Workers (CHWs) generate a huge amount of visit-level data: every household visit, assessment, and follow-up. On its own, this raw data is hard to use. Our CHW Monthly Activity Aggregation project turns those raw records into a clean monthly summary that's ready for dashboards and performance reviews. At a high level, this project is a dbt (data build tool) project that reads a fact table of CHW activities and produces a single, analytics-ready table: public.chw_activity_monthly, with one row per CHW per reporting month. Today's challenge: Managers often get raw logs (“John visited household 123 at 10:15”) instead of understandable summaries (“John visited 28 households in March, with 6 pregnancy visits”).

The Initial Use of Resources Imagine you have a one-acre plot of land in your village or hometown. You decide to build your dream house on this land, constructing a home for you and your family. You use the entire one acre of land to live comfortably. You have access to water, a garden, a park, and other resources, and you’re happily living in this space. After some time, you realize that even though you’re enjoying the one-acre property, you’re only using half of the land. The other half remains unused, meaning much of the land and its resources are going to waste. You then start thinking of ways to use the extra land more efficiently. Instead of letting that unused half-acre go to waste, you decide to build another property on it. You keep living in your original home with your family…  ( 9 min )

Submitted for Kiroween Hackathon 2024 - Skeleton Crew Category As a junior apps developer, I'd never built a RAG (Retrieval Augmented Generation) system before. The concept seemed intimidating: vector embeddings, semantic search, chunking strategies—all foreign territory. But the Kiroween hackathon's "Skeleton Crew" category sparked an idea: what if I could build ONE reusable skeleton that transforms into ANY AI personality? Seven days later, I had Project Corpus: a production-ready RAG chatbot that can become a professional legal assistant, a mystical spirit, or anything else—just by swapping a config file. 🔗 Live Demo | GitHub Repo Project Corpus is a document chat application with a twist: the same core logic powers radically different AI personalities. ⚖️ Legal Eagle Professional leg…  ( 10 min )

Terraform gets much easier to use once you understand its meta arguments. These arguments help you decide how many resources to create, how they should be linked, and how Terraform keeps track of them. In this article, we will break down the three most commonly used meta arguments: count, for_each, and depends_on. These are important to know if you're building AWS infrastructure with Terraform, especially when creating multiple resources or managing their order. count allows you to create multiple instances of the same resource using a simple number. It is the most straightforward way to scale resource creation. Example resource "aws_s3_bucket" "bucket_example" { count = 3 bucket = "my-bucket-${count.index}" } How it works count = 3creates three buckets. Each resource gets an index: …  ( 7 min )

Self-healing systems are basically computer systems that can fix themselves automatically when something goes wrong. Instead of waiting for a human to notice a problem and manually fix it ("reactive firefighting"), these systems are designed to be proactive. They are constantly watching (Continuous Monitoring) themselves to catch tiny signs of trouble or "degradation" (a slight performance drop or early error). When they find an issue, they automatically take steps to correct it (Automatic Correction). This might mean restarting a faulty component, rolling back a bad update, or isolating a sick part of the system. Why Self-Healing Is Important? Prevents outages before users feel them. Systems detect degradation (latency, memory spikes, failed health checks) and fix themselves before custo…  ( 7 min )

Model Context Protocol (MCP) has been wobbling on its own legs for a while now, which articulated a frustration many of us in the agentic space have felt but hadn't quantified: LLMs are exceptional code generators, but terrible state machines. The industry standard for agents is the ReAct pattern (Reason + Act), which essentially turns your LLM into a pseudo-runtime. The model decides on a tool, calls for the API, waits for the network response, parses the JSON result, and repeats. But here's the catch: this approach isn't exactly efficient with today's LLMs. You're basically asking a probabilistic engine to handle deterministic control flow, which is like using a neural network to do basic arithmetic. The result? Hallucinations, context window gets polluted fast, and state management bec…  ( 12 min )

A standard fintech workflow looks like this: Customer Onboarding: Capture user details. Trigger the KYC process. Receive verification c…  ( 9 min )

Subtitle: OAuth 2.0, JWT, Asymmetric Encryption, Zero-Trust, Hardening Headers, API Gateway, & Load Balancers. Most developers think security ends at: Login → JWT → Authenticated ❌ But enterprise-grade systems demand multi-layer security + zero-trust enforcement. 🛡️ Here is a practical, production-ready guide to hardening your Java architecture. OAuth 2.0 is authorization, not authentication. Your backend must treat every request as hostile. 📌 Core Flow: Client → API Gateway → Authorization Server → Resource Server 🧠 Zero-Trust Rules: ✔ Always verify WHO the user is. ✔ Always verify WHAT they can access. ✔ No implicit trust — even inside your VPC. ✔ Tokens should always be short-lived. 🔑 2.

The recent wave of tech layoffs has sparked fears that AI will eliminate software development jobs entirely. GitHub Copilot, ChatGPT and Claude can write code. Are developers obsolete? Not even close. But the answer isn't what the industry expects. Software development has chased the next big thing for generations, each promising to finally make coding accessible, efficient, or obsolete. The Visual Programming Dream emerged in the 1980s with languages like Prograph and DRAKON.

Today, I’m excited to share one of the most powerful updates we’ve added to DeployEase so far and honestly, this one changes everything about how developers interact with cloud infrastructure. Say hello to the DeployEase AI Assistant UI — your chat-powered deployment partner.🤖 Instead of navigating multiple menus, filling long forms, or remembering API endpoints… chat with an AI agent directly inside DeployEase. Just type what you want: 👉 “Deploy my repository https://github.com/… on a new server” “List my instances” “Scale up my production server” “Show me all deployments for server X” And the AI handles the rest intelligently, safely, and automatically. The magic behind the scenes comes from: MCP (Model Context Protocol) giving the AI full understanding of our backend API structure. Built-in user schema access keys so the AI never needs to ask you for credentials. Smart input validation — the assistant only asks the user for strictly required inputs (like selecting a region or deployment type). If the user is unsure, the AI auto-selects optimal defaults. Everything else triggering APIs, submitting jobs, fetching deployment results — is done seamlessly by the AI agent. In the example screenshot, I simply asked the AI: “Deploy my repository…” The assistant validated the inputs, prepared the deployment configuration, triggered the backend job, and replied: Deployment queued successfully That’s it. Deployment via conversation. This feature transforms DeployEase into: It finally bridges the gap between developers, cloud servers, and AI-powered automation.

It's a monthly newsletter about making Android apps more inclusive, and it covers accessibility, LGBTQ+ inclusion, support for different cultures and languages, privacy and safety for marginalized users, and more. In this post, I'm explaining why I'm starting it and what you can expect. The short answer is that I'm starting the newsletter because I'd love to read it, and there's nothing like it around. The longer answer is that these topics matter to me. Accessibility is a big part of my life, as you might know if you've read my blog posts, seen me speak at events, or followed me on social media. I'm also queer, and many of the issues I'm discussing are from what I've either ex…  ( 8 min )

✅ Explanation in Simple Terms Think of your app like a big office building with 200+ rooms (screens). Redux is the central storage room where shared files are kept. To avoid chaos: Each floor = a large feature (Payments, Orders, Users) Each room = a screen inside the feature Each file cabinet = slice (collection of related state + reducers) The main building manager = root store You NEVER mix files from different floors. Goal of Good Redux Structure Easy to find state related to a feature Easy to debug Easy to scale (add more screens) Shared logic goes into shared slices Feature logic stays inside feature folders ⭐ Recommended Structure for 200+ Screens /src ├── app/ │ ├── store.js │ └── rootReducer.js │ ├── features/ │ ├── users/ │ │ ├── api/ …  ( 10 min )

Medium vs DEV vs Hashnode vs Hackernoon vs CoderLegion — Where Should You Publish & Launch? 🚀 #webdev #opensource #productivity #techwriting #discuss In the past few months, I’ve spoken with many developers, indie founders, and open-source maintainers. Almost everyone eventually asks the same question: “Which platform is the best for posting my articles?” It’s a reasonable question — but it’s not the most important question. The question we should be asking is: Where should I launch my content?

CodePen runs weekly coding challenges, and this week's theme is Winter, focusing on Ice and Snow. I decided to participate by drawing an iceberg floating in the ocean. I found an iceberg image online that I liked and thought it would be fun to recreate it in CSS. At first, I considered using multiple elements, then switched to a single element, and eventually settled on drawing the entire piece with pure CSS and zero HTML elements. Whenever I share a zero-element drawing on CodePen, I add a small disclaimer: while the HTML panel may look empty, there is still some HTML. Specifically, I rely on the element, along with its ::before and ::after pseudo-elements, to create the artwork. There are also ways to achieve a true zero-HTML setup by applying the styles directly to :root and forcing the browser to render the CSS (this only works with Apache and Firefox, though.) So technically, this drawing could be achieved with pure CSS and absolutely no HTML elements. The drawing itself is fairly straightforward: body: the sky (a linear gradient) and two conic-gradient shadows body::before: the iceberg, shaped with a clip-path and shaded with conic gradients body::after: the water and waves, created using a repeating horizontal radial gradient plus a linear gradient for depth You can find the live demo and the source code on CodePen:  ( 7 min )

Docker images are already compressed when you push them to registries like Docker Hub, GHCR, AWS ECR, etc. So why would anyone compress an image again by using gzip or zstd? Because in the real world, engineers often need to: - move images between servers (air-gapped networks), - migrates registries, - backup image to object, - load or save images repeatedly in Continuous Integration (CI) pipelines. In these cases, docker save produces a raw .tar file often huge. But what’s the best compression tool? So we will test gzip vs zstd. Like I said before, you need to compress your image to: - transfer image between SSH or local network (LAN), - work with offline or air-gapped servers, - backup images to object storage, - migrate to new registry.

As the internet evolves, misconfigured permissions become a much bigger threat. Why? Because of two words: artificial intelligence—or, AI. Enterprise organizations have always needed tight control over their systems. Permissions are necessary for protecting access to resources, as well as meeting compliance rules and customer obligations. An over-permissioned user would be able to access sensitive information; for example, manager-level permissions that let an employee access their entire team’s salary when they should only be able to check their own. Once teams spot such mistakes, they can correct it and move forward without much disruption. That’s no longer true once AI enters the picture. AI agents do what humans do, from accessing data to sending emails. But unlike humans, they move th…  ( 12 min )

Understanding Why SaaS SEO Feels Different If there’s one thing I’ve learned working with early stage SaaS teams, it’s that SEO hits differently in this space. You’re not just targeting generic terms or chasing backlinks. You’re trying to show up for users who are actively searching for solutions to specific problems, often tied to workflows or niche industry issues. When I first helped a small SaaS team audit their content, we realized their blog was filled with broad topics that never aligned with user intent. That moment taught me how critical it is for SaaS companies to map content to actual product value. The Unique Challenge of SaaS Search Intent Unlike e-commerce or local businesses, SaaS search journeys are multi layered. Users don’t just search “software for invoicing” and then bu…  ( 8 min )

If you keep running into random blocks, login issues, or endless security checks, it doesn’t always mean you did something wrong. Many websites quietly run your connection through an IP blacklist test and a bot checker to decide whether to treat you like a normal visitor or a possible risk. An IP blacklist test checks whether your current IP address appears on lists of “bad” or risky IPs. Security companies, anti-spam providers, and some platforms maintain these lists to reduce spam, brute-force logins, scraping, and malware. Your IP reputation can suffer even if you did nothing wrong. For example: someone on the same Wi-Fi abused a service you use public Wi-Fi in airports, cafés, or coworking spaces your VPN or proxy endpoint is shared by many users the IP belongs to a datacenter ra…  ( 9 min )

In her recent interview, Julia Kasper, co-founder and CEO of Zukunftmoor, argues that rewetting drained peatlands represents the single biggest climate opportunity in agriculture today. Although peatlands cover only about 3 % of the global land surface, they store more carbon than all the world’s forests combined. When peatlands are drained, a common practice for agriculture, they don’t just release CO₂ once; they leak carbon continuously, year after year. Restoring peatlands thus stops that “constant leak,” and rewetting them can turn a major source of emissions into a long-term carbon sink. But rewetting alone is not enough: farmers need viable, sustainable livelihoods. That’s where Zukunftmoor’s innovative approach comes in. They propose combining rewetting with cultivation of Sphagnum moss — a natural plant of peatlands — which can serve as a sustainable substitute for extracted peat in horticultural substrates. This turns rewetting from a purely ecological restoration act into a market-driven, economically viable land-use model. By using drones or hand-seeding methods, and developing harvesting and substrate-supply chains, the approach offers farmers a low-input, long-term pathway to maintain income while restoring degraded peatlands. With this combination of climate mitigation and practical agriculture, Kasper’s vision offers peatland regions across Europe a concrete alternative to drainage-based farming — one that aligns environmental restoration with economic viability.

Spoiler Alert: This article is about using Mermaid diagrams as a method of re-enforcement in LLM prompting and not about the fary tail The Little Mermaid written by Danish author Hans Christian Anderson. You probably have seen a lot of Mermaid Diagrams already without even realizing that what is powering them is a formal description language which is very well understood by LLMs. Mermaid syntax is very good for describing formal, structural, or temporal information like "A happens, then B, and if X, then C". It forces clarity and guarantees that the visualization precisely reflects the text definition which makes it a perfect choice for a prompt as code approach. Complementing your text with additional Mermaid code in your prompt will provide the LLM so called "Dual-Path Reinforcement": T…  ( 10 min )

What are AI agents for scraping A user gives an LLM prompt for scraping. Agent breaks it down into subtasks and organize the work. Agent automatically asks for additional information if needed. The task is completed. AI agents for web scraping can perform assignments that previously required manual scripting. Separate tools already exist for searching, loading webpages, clicking buttons, and filling forms. Instead of executing them by hand, they can be combined and integrated into a unified research agent. AI agents use automatic scraping tools to: Navigate to a website. Handle interactions (clicks, scrolling, waiting for JS). Fetch HTML or rendered content. Parse and clean data. Output structured data (JSON, CSV, etc.).

THE MYTH You believe your six-figure salary means you are a creator. A builder. An engineer. You think that because you can stitch together a React frontend with a Firebase backend, you are practicing a high-level craft. This is a comforting lie. You are a technician. A digital plumber connecting pipes that smarter people built. THE PAIN This delusion makes you fragile. Your entire career is built on a framework that will be obsolete in five years. Your 'skill' is your knowledge of a specific API's documentation. You are infinitely replaceable. A cheaper developer from another continent, or a purpose-built AI, can do your job. You are a commodity, and the market is about to correct its overvaluation of your role. You are not building leverage; you are renting it. THE RED PILL The system do…  ( 9 min )

Model Context Protocol (MCP), has officially hit one year old as of November 25th and although there have been some amazing innovations within MCP, one issue still persists - the gaping security hole. This is no secret as just about every organization is talking about it. The long-running joke so far has been “The S in MCP stands for security”. Aside from prompt injections, MCP Server security is arguably the biggest issue in the AI security world right now. In this blog post, you’ll learn how to fix the gaps. To follow along with this blog post, you should have: A Kubernetes cluster running (it can be local). Kubernetes Gateway API CRDs installed, which you can find here. There are two forms of MCP servers: stdio StreamableHTTP stdio (the communication method) stands for standard input/ou…  ( 11 min )

Most search engines will show you pages that mention the same keywords. But what if you want to find articles that express the same ideas, even if they’re written completely differently? That’s the problem that pushed me into building something new. A few months ago, I needed to verify whether parts of my content were being reused online. Google wasn’t helpful — keyword search missed half of the semantically similar pages. Rephrased paragraphs were completely invisible. So I built my own engine. Today, I’m excited to introduce Nooth, an AI-powered system that takes any text you enter and searches the web for content with similar themes, ideas, and semantic meaning. Drop in a paragraph → get URLs, similarity percentages, and deep analytical insights. Here’s how it works under the hood. 🚀 T…  ( 8 min )

The Nop platform does not use common GraphQL open-source libraries such as graphql-java; instead, it implements the NopGraphQL engine from scratch. The NopGraphQL engine introduces many novel implementation approaches that broaden GraphQL’s scope of application and enhance its practicality. For detailed documentation, see graphql/index.md GraphQL requires the frontend to specify the fields to be returned, which can be cumbersome when there are many fields. In such cases, you can use the Fragment feature of the GraphQL language to define common field sets and reference these fragments in queries to simplify them. F_ Each backend service object in the Nop platform has an associated XMeta metadata model file, where you can augment GraphQL types with additional metadata. <selections…  ( 9 min )

The European regulatory environment for crypto is evolving rapidly, and MiCA is the most significant development shaping how businesses operate across the European Union. Companies launching exchanges, custody solutions, OTC desks, tokenization platforms or payment systems must now comply with a unified regulatory structure that is far more demanding than the previous patchwork of national rules. Preparing for authorization requires a strategic, methodical and well-organized approach that goes far beyond producing a few basic compliance documents. MiCA introduces a new regulatory architecture designed to ensure consumer protection, market integrity and financial stability. It defines a complete framework for authorization, governance, internal controls, AML procedures, ICT security, operat…  ( 8 min )

UX Design: Turning Website Visitors into Customers & Boosting Conversion If you’ve ever stared at your website analytics and thought, “We’re getting visits… so why aren’t people buying?”, you’re not alone. Many businesses assume they have a marketing problem when, in reality, they have a user experience problem. Think of UI/UX design as the bridge between intention and action. People land on your website with a goal. They want information, pricing, clarity, or confirmation. If that path is confusing, slow, or hard to navigate, they don’t complain; they leave. Investing in UI/UX isn’t about making your website “look nicer.” It’s about making it usable, trustworthy, and purchase-friendly. That’s how visitors turn into customers. Before diving into design tactics, we need to talk about conv…  ( 11 min )

Arch gives you the steering wheel and the broom. On my Arch setup, Limine boots a BTRFS root while Snapper snaps a before/after every time I poke pacman. It's gorgeous, rollbacks for days, but the snapshots stack up faster than RGB stickers unless I sweep them out. So I wrote this simple cleanup.sh, my tiny digital janitor. "I use Arch btw." Pacman + Snapper hooks = instant safety net. If a wile build breaks stuff, I just reboot, pick the previous snapshot in Limine, and carry on. I settled on CachyOS and HyDE on top of it, after trying and experimenting with multiple setups. Now CachyOS loves performance tweaks, which means I love experimenting. Snapshots let me go full mad scientist without sweating the fallout. Doing the cleanup myself keeps that classic Arch vibe: I decide what stays, …  ( 8 min )

When crafting user interfaces, designers and developers often need to present visuals, forms, and scripts before real data is available. Mock elements, placeholders and fictional samples, make this possible with both clarity and tradition. Below are some of the most famous placeholders and their backstories. Mock elements act as stand-ins for actual content, helping designers and clients focus on visual structure, usability, and layout, undistracted by real-world data or identities. They keep prototypes relevant, flexible, and safe for sharing and testing while enabling early feedback and iteration.

YAML is a great file format, used for writing configuration files; and more and more, as a foundation for Domain Specific Languages (DSLs), such as the ones for Docker and Kubernetes. We have all, however, suffered from a frustration: YAML is fundamentally a static file format. How can we make it dynamic? It starts with the fact that some string, like http://dev.company.local appears several times across the files. server: url: http://dev.company.local ... documentation: url: http://dev.company.local/docs ... And the day that address changes, what do we do? Do a search/replace in the config files? Nah... this is brittle and things will get worse before they get better. And in any case, it doesn't solve many cases where a "small" change of parameter (from dev to test and from te…  ( 8 min )

contributors: @parin-k, @sumit12dec If you're familiar with a payments company, you know the drill. Risk agents manually review thousands of merchant websites every month, checking for red flags: sketchy privacy policies, misaligned pricing, questionable social media presence, suspicious domain registration patterns. At Razorpay, our risk operations team was conducting 10,000 to 12,000 manual website reviews monthly, each taking roughly four minutes of human attention. That's 700 to 800 human hours consumed every month, and the quality was inconsistent because different agents would interpret the same signals differently. The traditional approach to fraud detection involves throwing bodies at the problem or building rigid rule engines that break the moment fraudsters adapt their tactics. …  ( 13 min )

The momentum around Generative AI isn’t slowing down if anything, it’s accelerating. Just last year, everyone was talking about its potential, but this year the impact has multiplied exponentially. Across industries, leaders are waking up to the fact that bold, strategic adoption of GenAI determines whether a business falls behind or rises above its competition. Yet, despite all the hype, there’s a surprising data point: while 90% of software development professionals use AI daily, only 13% of enterprises are actually thriving with it. Why such a massive success divide? The truth is simple: winning with GenAI depends on how well an organization manages its data and integrates AI-powered business solutions into its ecosystem.

Refactoring becomes easier when you receive fast feedback about improvement options in code. GitHub Copilot Chat already helps with this, but writing a long prompt each time feels wasteful. A small prompt instruction file in your repository removes friction. This article walks through one concrete example.

You reference such a file from chat with a slash command instead of copying full text again. This section focuses on one refactoring helper prompt. Create folder .github/prompts in your repository if it does not exist yet. Add a new markdown file named refactoring_opportunities.prompt.md inside this folder.

The Misunderstanding That Reveals the Future “They told us: ‘The EU AI Act is coming — better prepare.’ But what if some of us didn’t need to prepare? What if we built for that world before the ink dried on the legislation?” Some see the upcoming regulation as another compliance burden. We built TAUGuard — not as a response, but as the foundation. The advent of regulation such as the EU AI Act, alongside standards like ISO 42001 and frameworks such as NIST RMF, signals a tectonic shift: From retrospective compliance (reports, audits) → to real-time assurance. From static documentation → to dynamic, executable compliance. From paper‑trail governance → to code-anchored governance — fresh, live, unforgeable. In other words: laws and standards no longer ask whether you did it — the…  ( 7 min )

Branch development is a key aspect of software development. The idea here is you clone (i.e. copy) the code you’re going to work on onto your own computer, then you can make your necessary changes, then lastly save it back to the official code repository. In other words, you take the copied code and “branch” off with it to make changes. Then you “merge” your branch back into the main repository of code. In my old job, Pega handled this on it’s own. It had it’s own branching tools, so I could copy the low code settings into my own branch, make my changes, then check them back in to the official code. But outside of low-code tools like Pega, developers primarily use git to help manage their branch development. With 100Devs, I’ve been pushing the HTML and CSS projects into Github.

Imagine waking up in 2035. You buy coffee, pay rent, send funds abroad… and at no point do you think: Should I convert first? Because you don’t need to. The rails under the system do that for you. That’s the world Crypto-as-a-Service (CaaS) is quietly building. Platforms like Coinbase CaaS and WhiteBIT CaaS are basically the hidden rope tying fiat and crypto together. Users pay as usual, but behind the scenes, assets swap, settle, stake, and move across chains without friction. It’s not “using crypto.” using money. This is what adoption actually looks like - not flashy slogans, but infrastructure that disappears into the background. Absolutely - not because they suddenly become blockchain experts, but because crypto will blend into their daily routines. Convenience always wins. When people don’t need 12 tabs open, a gas calculator, a prayer, and a Ledger update just to move $50, adoption skyrockets. Crypto will feel less like an “industry” and more like the default financial layer of the internet. Modular chains, tokenized assets, real-world rails, even AI-driven compliance - all of it pushes us toward a system where money works faster, cheaper, and more globally than legacy finance ever could. When crypto becomes truly mainstream… And that’s a feature, not a bug. 👉 If you want to dive deeper into how CaaS shapes this future, you can find more info here.  ( 7 min )

Your stakeholders are calling. The Product Owner is pacing. You start hearing that classic, self-soothing lie: "It works on my machine!" No, champ, it doesn't. You've walked right into N+1 query hell, and you didn't even pack a bag. Look, ORMs (Object-Relational Mappers) are great. They let junior devs—and let's be honest, exhausted senior devs—write complex database operations without remembering the exact syntax for a LEFT OUTER JOIN. But they also make it ridiculously easy to accidentally turn one simple data request into a thousand database trips. The N+1 problem happens when you need a collectio…  ( 8 min )

In part one, we explored the basics of Java multithreading, including threads, processes, and how to create threads using Thread and Runnable. In this second part, we’ll go deeper and cover essential concepts like thread control methods, synchronization, inter-thread communication, daemon threads, and Java concurrency utilities. Thread Control Java provides built-in methods to control thread execution. sleep(): Pauses the current thread for a given time. join(): Waits for another thread to finish. yield(): Suggests that the current thread should pause for others to execute.

I'm hitting a wall. Yesterday, I spent 15 minutes arguing with an AI agent that insisted my error handling logic was "redundant." It wasn't. It was catching a specific edge case the AI didn't have context for. I love the speed, but the noise is killing me. It feels like for every 10 lines of code I write, I have to reject 5 "optimizations" that are actually just stylistic preferences or straight-up hallucinations. It’s not just the hallucinations. It’s the confidence. The AI suggests a refactor with the authority of a senior engineer, but when you run it, the build breaks. I'm curious—what's the most confident but wrong suggestion an AI has thrown at you recently? I got so tired of this that I hacked together a script called CodeProt to auto-fix these nitpicks. It's still a WIP but saves me hours.  ( 6 min )

WTF is this: Unpacking the Mysterious World of Distributed Data Warehousing Ah, data warehousing – the ultimate party crasher of the tech world. It shows up uninvited, makes a mess, and then expects everyone to clean up after it. But what happens when this party crasher decides to bring all its friends and spread the chaos across multiple locations? Welcome to Distributed Data Warehousing, folks! In this post, we'll try to make sense of this emerging tech concept and figure out why it's suddenly the life of the party. What is Distributed Data Warehousing? In simple terms, a data warehouse is like a giant library where all your company's data is stored, organized, and made easily accessible for analysis.

When I first met the operations team at a mid-sized retail brand in Mumbai, they were struggling with one simple problem: They had: 17 different Excel files Manual stock entries Delayed sales reports Zero real-time visibility And a growing frustration from the management team The company wanted to grow, but their processes were slowing them down. That’s where Wisecor Transformation stepped in. Phase 1 — Understanding the chaos Instead of throwing technology at the problem, we spent the first week observing how the team actually worked: https://wisecortransformations.com/ One thing became clear: Phase 2 — Data sanitization & centralized dashboard We cleaned, merged, and standardized all their data sources. Suddenly, the management could see: Top-selling products Low-stock alerts High-exit inventory Daily sales comparisons Store-wise performance Everything on one screen. Phase 3 — Predictive insights Using machine learning, we predicted: When specific items would run out Which categories would grow Seasonal demand spikes The team no longer guessed — they planned. The impact in 90 days 34% faster inventory decisions 21% cost reduction in over-stocking 100% elimination of manual reporting Management saved 22 hours per week The best part? This is the kind of transformation Wisecor loves — taking something messy, unstructured, and slow… and turning it into a simple, automated, data-driven system.  ( 7 min )

Two years ago, I was sitting in my room at home, completely stressed out about my future. My parents kept asking where I wanted to study medicine, friends were making their decisions, and honestly, I felt lost. I googled “best affordable medical schools” about a hundred times. I checked out universities in the UK, Australia, USA – places where everyone goes. But the fees? They made my head spin. I literally showed my mom the numbers and she went pale. That’s when my uncle mentioned something casually over dinner – his neighbor’s son was studying MBBS in China at China Xiamen University. I remember thinking, China? Really?

TL;DR: On December 1st, 2025 - my birthday - I released Born v0.5.0. Not because the version number was nice, but because that was the day we successfully trained our first Hierarchical Reasoning Model in pure Go. Nine months of preparation. Two weeks of intense labor. One framework that makes production ML in Go a reality. I've been writing Go for years. Love the language. The simplicity. The tooling. The "it just works" deployment story. But every time I needed machine learning? Back to Python. TensorFlow. PyTorch. Docker images. Dependency hell. The whole circus. For years I kept asking myself: Why can't we do ML in Go? Sure, there were attempts. Gorgonia. GoMLX. Brave projects, but none of them felt like a complete answer.

The Problem I Can't Ignore You know that feeling when you open LinkedIn and see another "I'm humbled to announce..." post? Or someone turning a simple job change into a 12-paragraph hero's journey? Yeah, me too. As developers, we're not great at the corporate networking thing. We want to show our work, share our side projects, maybe find some freelance gigs—but without the performative professionalism that makes LinkedIn feel like a never-ending job interview. So I'm building Brand Builder - a personal branding platform designed specifically for people in tech who want to showcase their work without the corporate cringe.

Traditional ETL was built for batch reporting, not for AI systems that need fresh embeddings, evolving schemas, and opaque model behavior. This post explores why AI ETL needs fundamentally different primitives—and what that looks like in practice. Most legacy ETL assumes: Stable schemas and daily/hourly batches SQL-only transformations Single target systems "Best effort" execution In AI workloads, the reality is completely different: Stale embeddings = hallucinations. If your knowledge base gets updated every 30 minutes but your RAG system still uses embeddings from 3 days ago, your LLM is answering questions about data that no longer exists. Schemas evolve constantly. Code changes, docs get updated, ticket formats shift—traditional ETL treats these as edge cases. For AI, they're the norm.…  ( 9 min )

Technology has come a long way, but no system is ever completely safe from failure. Over the years, I’ve worked on and designed systems that try to reduce the risk of outages or failures, but nearly all systems experience some kind of downtime. Even the big companies are not immune to it, so how do they make sure their systems and services are reliable when something inevitably goes wrong? That’s where chaos engineering comes in. It’s a practice that helps teams build more resilient systems by finding weaknesses before they cause real outages. In this blog post, we’ll explain what chaos engineering is in simple terms, how it relates to DevOps and Site Reliability Engineering (SRE). Chaos Engineering is a methodology that IT teams can use to identify vulnerabilities in complex systems b…  ( 8 min )

Developers like automation. GitHub Copilot Agent writes code, runs tests, edits files. This speed hides a risk. The agent starts changing code before you see a plan. You need a brake. A short sentence in your prompt gives you control. Describe the changes you want. Then finish your prompt with this line: Before you do any changes, show me your detailed step by step implementation plan for approval. You ask the agent for a plan first. No edits yet. Only a clear list of steps. Afterwards you review the plan. You confirm, refine, or reject. A plan first pattern improves the flow. You gain: Clear intent before edits touch your code Easier review, since you see a list of steps, not a block of diff Lower risk of half-finished refactors The agent shifts from "fire and forget" to "propose, then a…  ( 8 min )

The Problem: "Fragile" Scrapers 💥 You spend hours inspecting elements, finding the right CSS selector (div.product-card > span.price), and building your logic. It runs perfectly for a week. Then, the website updates its UI. The class names change from .price to .p-4 text-bold. Your scraper breaks. I got tired of this cycle. So, I decided to build a scraper that doesn't read code. It "sees" the page, just like a human does. The Solution: Multimodal AI (Gemini 1.5 Pro) 👁️ Here is how I built this workflow in n8n. Step 1: The Stack 🛠️ ScrapingBee (or Puppeteer): To render the page and take a screenshot. Google Gemini 1.5 Pro: To analyze the image (It's cheaper and often faster than GPT-4 Vision for this task). Step 2: The Logic 🧠 Render & Screenshot First, don't fetch the HTML. Fetch a Binary Image. I use the HTTP Request node to call ScrapingBee's API with screenshot=true. This returns the visual representation of the website. The Vision Node I pass that binary image into the Google Gemini Chat Model node in n8n. The Prompt (The Secret Sauce) This is where the magic happens. You need to be very specific to get clean JSON. My Prompt: "Analyze this image of an e-commerce product page. Extract the Product Title, Price, and Availability status. Return the data ONLY as a valid JSON object. Do not include markdown formatting or backticks." The Output The AI looks at the pixels—not the code. Even if the website obfuscates its HTML classes, the AI still sees "$19.99" in big bold text. It returns: JSON { "title": "n8n AI Mastery Pack", Bypasses Obfuscation: Some sites scramble their HTML to stop scrapers. Vision AI doesn't care. Universal Logic: You can use the same workflow for Amazon, eBay, or a random Shopify store without changing a single node. The Trade-off ⚖️ Want the Workflow? 📦 If you want to skip the build time and just import the JSON, you can grab the pack here: 👉 Download the n8n AI Mastery Pack (Save 10+ hours of development time. It includes the exact Vision Logic I described above.)  ( 7 min )

Before this, “AI agents” sounded complicated. AI agents are like helpful teammates they don’t just answer questions, they can think, decide, and take action. Here are the biggest insights I took away: A chatbot replies. You can teach an agent to use an API, look up data, or perform actions. Good agents don’t forget. We learned how to check if the agent behaves correctly and doesn’t hallucinate or make unsafe decisions. You don’t need deep AI knowledge. Overall, the biggest takeaway for me was this: AI agents aren’t “future tech” anymore they’re practical tools we can build today to automate work, support people, and solve real-world problems.

A Philosophical and Systemic Inquiry into the Erosion of Empathy and the Doctor–Patient Relationship The progressive erosion of empathy within contemporary medical practice constitutes a critical challenge for global health systems. Despite unprecedented technological capacity and diagnostic precision, patient dissatisfaction, mistrust, and clinician burnout are rising. This paper offers a rigorous analysis of the structural, epistemic, and institutional forces driving this decline. Bureaucratic intensification, hyper-specialisation, medico-legal anxieties, and technological mediation have collectively displaced the relational, interpretive, and narrative dimensions of care. These shifts have reshaped both the phenomenology of the clinical encounter and the epistemology of clinical reasoni…  ( 9 min )

Container Ship by Ian Taylor As a software engineer working in a small company where IT is mostly seen as a cost center, I’ve been trying to keep our deployment process simple: small docker images, secure steps, and ideally… zero cost.

Supply chains rarely operate in neat, single-step workflows. Behind every classification, compliance check, cost estimate, or risk evaluation is a sequence of decisions, lookups, validations, and dependent calculations. Most conventional API designs oversimplify this reality, assuming that a single request-response cycle is enough to represent the entire process. Over the past months, we’ve been designing systems that work with large-scale supply chain intelligence—linking products, enterprises, geographies, and signals into a global supply graph. Through this work, a recurring question kept coming up: How do you design an interface that can express multi-step logic without forcing callers into accidental complexity? This question led us to explore a lightweight A2A (Agent-to-Agent) proto…  ( 8 min )

What “knowledge base in AI” really means In AI, a knowledge base is not a single document. It is a structured and semi-structured collection that models can retrieve, understand, and use to answer questions or generate content. Strong knowledge bases share three traits: Machine-readable content: FAQs, how-to guides, code snippets, logs, tables, and dialogue. Rich metadata: topics, tags, sources, timestamps, trust scores. Continuous upkeep: versioning, review workflows, user feedback loops. Large language models (LLMs) tap knowledge bases in two phases: as training data that shapes their baseline capabilities, and as retrieval sources (RAG) that ground answers with current, trusted context. A plain-language definition and why it matters for LLMs. The difference between traditional KBs and…  ( 9 min )

Assistant: 它就会预测接下来一个词是啥。 这个预测过程叫 forward pass。 你们没有改模型结构 —— 使用的是老师给的 GPT-2。 Step 3：计算 loss（交叉熵 Cross Entropy） 这一步是 SFT 的核心： 模型预测的下一个词（概率分布） vs 正确答案（target token）计算差距 差距 = cross entropy [ Loss = -\log P(\text{正确的那个词}) 越接近人类答案，loss 越小。 这个过程是自动的，你们组的代码已经写好了。 Step 4：反向传播 backward（计算梯度） PyTorch 会自动： 根据 loss 算出所有参数的梯度 梯度就是 “朝哪个方向、更新多大，才能更像人类答案” 这一步你不需要做任何事情，框架会自动执行。 Step 5：优化器 update 参数（你负责的部分） 这一步就是： optimizer 用梯度更新模型，让下一次预测更准确。 默认是 Adam， 换成各种优化器，比较效果。 包括： SGD SGD + momentum Nesterov Adam AdamW 你的工作是整个流程中 唯一的需要你理解数学的环节。 Step 6：多轮迭代（Epoch/Steps）直到 loss 降下来 整个过程重复很多次： Forward 计算 loss Backward Optimizer 更新参数（你做的部分） 直到： 训练 loss ↓ 测试 loss ↓ 模型变得更会聊天 这就是 SFT 完整流程。 我做的部分正好是 Step 5： 研究“用什么方式更新模型参数”会影响： 并且你画出了图（SGD vs Adam）并解释了原因。 请记住： 【别人问：SFT 是什么？流程是怎样的？】 你说： “SFT 就是用带答案的对话数据，让 GPT-2 学习怎么模仿人类回答。过程就是： 这段你以后永远可以用。 【别人问：那你做了哪部分？】 你说： “我负责的是训练过程里的优化器部分。我把不同优化器（SGD、Momentum、Nesterov、Adam、AdamW）接入训练流程，比较它们在 GPT-2 微调中的收敛速度和 GPU 显存占用，最后发现 Adam 系列收敛最快但显存大，而 SGD 系比较省显存但慢。” 这句话精准、真实、你自己能理解。 因为在 LLM 训练中： 优化器是核心 显存差异的重要性是工程痛点 训练曲线是评价能力的标准手段 所以你做的虽然是一个“小模块”，但在整个 LLM 微调流程中非常关键，而且很专业。 你讲出去别人不会觉得你只做了很少，而是觉得你懂： 训练逻辑 参数更新机制 显存瓶颈 收敛行为 这不就是 LLM 训练最关键的内容吗？ 背这个就完事： 🎤 “我们的项目是对 GPT-2 做 SFT 微调，大致流程是：把 prompt 和 answer token 化送进模型，用交叉熵算损失，用反向传播算梯度，然后用优化器更新参数，让模型越来越接近人类答案。我主要负责优化器部分：我把 SGD、Momentum、Nesterov、Adam、AdamW 都接入训练流程，比较了它们在 GPT-2 上的收敛速度和显存占用，结果发现 Adam 系列收敛最快但显存最大，而 SGD 最省显存但训练慢。这让我真正理解了 LLM 微调里优化器对训练动态和 GPU 资源的影响。”  ( 6 min )

Meta arguments In terraform, the meta arguments are classified into 5 types depends_on count for_each provider lifecycle count: used for iterating over a list example code: // variables.tf variable "bucket_count_list" { type = list(string) default = [ "bhaskaratejabulusu-bucket-day-08-list-1", "bhaskaratejabulusu-bucket-day-08-list-2" ] } // main.tf resource "aws_s3_bucket" "bucket1" { count = length(var.bucket_count_list) bucket = var.bucket_count_list[count.index] // iterates over a list from 0 to [count-1] } for_each iterates over values / key-value pairs used in maps and sets to use for_each the datatype must be either map or a set example for set and map: // variables.tf // set variable "bucket_count_set" { type = set(string) default = [ "bhaskaratejabulusu-bucket-day-08-set-1", "bhaskaratejabulusu-bucket-day-08-set-2" ] } // map variable "bucket_count_map" { type = map(string) default = { "bucket1" = "bhaskaratejabulusu-bucket-day-08-map-1", "bucket2" = "bhaskaratejabulusu-bucket-day-08-map-2" } } // main.tf // using set resource "aws_s3_bucket" "bucket2" { for_each = var.bucket_count_set bucket = each.value // iterates over the set using a for loop internally and retrieves every value } // using map resource "aws_s3_bucket" "bucket3" { for_each = var.bucket_count_map bucket = each.value } depends_on example: // main.tf resource "aws_s3_bucket" "bucket1" { count = length(var.bucket_count_list) bucket = var.bucket_count_list[count.index] } resource "aws_s3_bucket" "bucket2" { for_each = var.bucket_count_set bucket = each.value depends_on = [ aws_s3_bucket.bucket1 ] } In the above code, the bucket2 is dependent on bucket1 so terraform will wait for bucket1 to be created and then bucket2 will be created ensuring the correct order. @piyushsachdeva  ( 7 min )

The world of mobile apps in 2026 runs on context and personalization. Users expect apps to be smart, responsive, and respectful of their privacy. At the heart of this evolution is React Native background geolocation, which has moved far beyond simple GPS tracking. By 2026, implementing location services is less about dropping pins on a map and more about building intelligent, battery-efficient systems that understand user context. This guide covers the advanced features, privacy demands, and implementation strategies you need to succeed. Location tracking is no longer a niche feature. It's a core component of modern app experiences, but the technology and user expectations have changed completely. Simple coordinate tracking is obsolete; intelligent, privacy-first systems are now the standa…  ( 13 min )

LinkedIn just killed the carousel hack. You know the one. That "swipe for more" format that dominated feeds for the past two years, promising insights while delivering mostly repackaged platitudes with nice gradients. The 2026 algorithm changes—rolling out in phases starting January—represent the most significant shift in how B2B content gets distributed since the platform decided it wanted to be a "creator economy" player back in 2023. And honestly? It's about time. I've spent the last three weeks digging into LinkedIn's official guidance, testing content variations, and talking to folks who've seen their reach either crater or explode in the beta rollout.

When you hear people in tech talk about SSH, they're usually referring to a way of securely connecting to another computer over the internet or a network. The full form of SSH is Secure Shell. At first, that might sound abstract, so let's start with a simple picture. Imagine you have a computer at home, and another one sitting in a data center somewhere far away. You want to log into that remote computer and run commands, just as if you were sitting in front of it. That's exactly what SSH allows you to do, but in a safe and encrypted way. SSH stands for Secure Shell. It's a cryptographic network protocol that lets you: Log into remote computers securely Execute commands on machines you can't physically touch Transfer files without anyone snooping Create encrypted tunnels for other network …  ( 12 min )

Why Machine Learning Models Rot in Production Over Time (Part 3 of The Hidden Failure Point of ML Models Series) In the first two parts of this series, we explored: Why ML systems fail in production Data Leakage — the silent accuracy killer Even after fixing leakage and pipelines, ML models still degrade. Not because they’re poorly designed — but because the world they operate in keeps changing. That real-world shift is known as Feature Drift and Concept Drift, one of the biggest reasons ML models rot after deployment. All ML models decay. Not due to code bugs, but due to shifting data and behavior. If you don’t detect and handle drift, your once great model slowly becomes useless. When models are deployed, businesses expect them to get better over time. What actually happens is: Ti…  ( 8 min )

Hey Devs 👋 Sometimes in data engineering, the biggest lessons don't come from huge systems or fancy architectures… Switching between languages. Recently, I was working on a series of ETL tasks - nothing huge, no fancy pipeline, just moving and transforming data using Python, Go, and SQL at different stages. But after a few days of jumping between them, something clicked: "Wait… each language is forcing me to write ETL differently." And that thought basically became the reason for this post. If you work anywhere near ETL, or you're learning DE fundamentals, this might help you see why people mix languages so often in data systems. It started with a small exercise: clean raw data → Python push the processed data efficiently → Go shape it inside the database → SQL The task itself wasn't…  ( 8 min )

Think of it as a universal adapter that allows AI models like Claude to safely access your databases, APIs, file systems, and business tools. S…  ( 11 min )

JavaScript has evolved far beyond a simple browser scripting language. Today, it is the backbone of modern web development and one of the most in-demand technologies across the industry. Whether you’re building web apps, mobile apps, servers, or even AI tools, JavaScript plays a central role in shaping the digital world. Below are the key reasons why JavaScript is more important than ever. 1) JavaScript Runs Everywhere Unlike most languages limited to specific platforms, JavaScript works across: Browsers Mobile apps (React Native, Ionic) Desktop apps (Electron) Backend servers (Node.js) This makes it one of the most versatile languages in the world. 2) Massive Ecosystem & Community Support With millions of developers and countless packages on npm, JavaScript has: Fast solutions for common …  ( 7 min )

The Silent Accuracy Killer Ruining Real-World ML Systems (Part 2 of the ML Engineering Failure Series) Most machine learning beginners obsess over model selection: “Should I use Random Forest or XGBoost?” “Will Deep Learning improve accuracy?” “How do I tune hyperparameters for best results?” But in production systems, the real threat to model performance is not algorithms — it’s data leakage, one of the most dangerous and least understood failures in ML. Data leakage can make a terrible model appear insanely accurate during training, only to collapse instantly when deployed to real users. Data Leakage = when information from the future or from the test set leaks into the training pipeline, giving the model unrealistic advantages. It’s the ML equivalent of cheating on an exam — scoring…  ( 8 min )

What Is an API, and What Are Web APIs? These types of APIs are often divided into two main categories: browser APIs and third-party APIs. Browser APIs expose data from the browser. As a web developer, you can access and manipulate this data using JavaScript. They also provide access to various functionalities, such as manipulating the structure of the website, handling events, working with storage, and communicating with the network. Some examples of commonly used Browser APIs include: The DOM API, which you can use to manipulate HTML elements, their styles, and attributes. You will learn much more about the DOM in the coming lessons. It’s a core concept in web development. The Storage API, to store data locally on the user’s device.

⏱️ Reading time Post-airdrop chaos isn't random. It's a predictable structural failure in expectations management. The airdrop "mercenary" isn't here for your technology or vision. They're hunting profit. When that profit expectation gets crushed, whether through Sybil detection or an allocation smaller than imagined, the response is swift and brutal: FUD (Fear, Uncertainty, and Doubt) weaponized as revenge. *85% of eligible addresses received between $100 and $500. This isn't a philosophical problem. It's a tactical one. The outdated approach of "ignore the haters" doesn't work anymore.

Even the best developers make simple mistakes — not because they lack skill, but because they overlook small details under pressure. Here are the top 10 dev mistakes and the real reason behind each: 1) Forgetting Active/Inactive Status Updates Why? Small flags get ignored while focusing on major logic. Later, UI breaks. 2) Hardcoding Values Why? “Temporary” fixes that become permanent and cause issues in production. 3) Skipping Validation Why? Developers rush to make the feature work, validation comes last. 4) Ignoring Error Logs Why? Warnings look harmless — until they explode later. 5) Not Handling Null or Empty Data Why? Assumption that data will always exist (it never does). 6) No Comments in Code Why? “I’ll remember this later.” No one ever does. 7) Missing Migrations or DB Sync Why? Local works fine → live breaks. Classic mistake. 8) Poor Folder/Code Structure Why? Speed over maintainability during development. 9) Weak Error Handling (no try/catch) Why? Developers build for success paths, not failure. 10) Direct Push to Main Branch Why? “Quick fix” mindset. Leads to bigger problems. Developer Reminder Most dev mistakes aren’t technical they’re habit-based. Small improvements in workflow can save you hours of debugging and make you a stronger engineer.  ( 6 min )

When I first released Blazor Developer Tools, I had a simple goal: give Blazor developers the same component inspection experience that React developers have enjoyed for years. React DevTools lets you see your component tree, inspect props in real-time, and understand your application's structure. Blazor had nothing equivalent. The v0.9 release was a working MVP, but I always knew the architecture had fundamental limitations that would eventually hit a wall. After weeks of studying the Blazor source code and exploring dead ends, I've arrived at a completely new architecture for v0.10 that solves these problems at the framework level. This post explains what I learned, the options I considered, and why the new approach works. The v0.9 architecture was clever but ultimately a workaround. Her…  ( 13 min )

One of the most effective ways to learn functional programming is to convert the same features you've written in an OOP language to functional style. In this post, I won't go into theoretical details about functional programming. Instead, I'll implement and compare a concrete example to highlight the differences between thinking in OOP vs functional paradigms. For example, I have a ToyRobot object in Ruby.

Simple RAG vs Agentic RAG -Why Your AI Needs to Think, Not Just Search Ever wondered why we need Agentic RAG when Simple RAG already retrieves answers? Let’s make it tangible with an analogy. HATEOAS (Hypermedia as the Engine of Application State) is a design principle for APIs: Instead of giving you a single static response, the API provides links or next actions to explore. This allows clients to navigate intelligently and discover related resources. We can use this idea to understand RAG: Simple RAG = A single REST call You query /recipe/chocolate-cake → you get one recipe. Fast, straightforward, but limited—you only see what’s returned. Agentic RAG ≈ HATEOAS-inspired exploration You query /recipe/chocolate-cake → the system returns the recipe and dynamically decides what else to fet…  ( 7 min )

Developers love to pretend their Dockerfiles are perfect until a build takes eight minutes and the image balloons bigger than a AAA game update.

Quick Demo Introduction There have been an increasing variety of coding agents recently. Each one getting more integrated and comprehensive than the last. I've been lucky enough to have been able to try a couple of these not only on my own free time, but as part of an implementation task at my work to integrate these agents into some of the development workflows. I remember trying CrewAI, a multi-agent AI system, and trying to hack together our own coding agent. It did well enough... but it's not what CrewAI was meant for. Then Codex came along and did what our hacky system did way better and more precisely with fewer errors. The learning experience was valuable nonetheless. Because that's what it was meant for. It reads your codebase and prepares itself with the right con…  ( 16 min )

Chip Design Breakthrough: Predicting Performance Before Layout Tired of lengthy design cycles and performance surprises late in the game? Imagine knowing your chip's power consumption and speed before committing to the physical layout. That's the promise of a new machine learning approach that's revolutionizing how we design integrated circuits. The core concept is to build a predictive model that learns from the early stages of design, specifically the netlist. This model is then fine-tuned to estimate parasitic effects – the unwanted capacitances and resistances that arise from the physical layout – and predict final performance metrics like timing and power. Think of it like predicting the taste of a cake based on the recipe (netlist) while accounting for how your oven (layout tools) …  ( 7 min )

A secret is any piece of sensitive information that must be protected from unauthorized access. Examples: API keys Access tokens Database passwords Private keys (.pem) Confluent Cloud credentials Terraform backend credentials OAuth tokens SSH keys Goal: Keep secrets encrypted at rest, encrypted in transit, and never stored in plaintext (repo, logs, artifacts). 2. WHY SECRETS MANAGEMENT IS CRITICAL A senior DevOps engineer must prevent: Credential leaks Unauthorized access Accidental commits to Git Hardcoding in Terraform, Kubernetes, Docker, or CI/CD Secrets leaks cause: Environment compromise Data breaches Unauthorized AWS usage costing thousands Repository takeovers This is why we use secure secret stores, not files. 3.

Last Tuesday, a founder asked me: "Should I build a mobile app or a web app first?" I asked her three questions: Where are your users when they need your product most? Can they accomplish the core task on a laptop? Do you have 16 weeks or 8 weeks to validate your idea? She went quiet. Then: "I haven't thought about any of that." Most founders haven't. They just know they need an app—capital A, as if "app" only means one thing. Let's fix that, because this decision will either accelerate your startup or drain six months before you realize you chose wrong. Here's what nobody tells you: The "right" platform isn't about what's trendy or what your competitor built. It's about where your specific users need to solve their specific problem.

The other day, I released a C# library called Linqraft! In this article, I'd like to introduce it. C# is a wonderful language. With powerful type safety, a rich standard library, and the ability to handle everything from GUI app development to web development, I think it's an excellent language for almost any purpose. However, there's something about C# that has been frustrating me on a daily basis. That is: "Defining classes is tedious!" and "Writing Select queries is tedious!" Since C# is a statically-typed language, you basically have to define all the classes you want to use. While this is unavoidable to some extent, having to define derived classes every time is extremely tedious. DTO (Data Transfer Object) every time, resulting in writing similar class definitions over and over agai…  ( 13 min )

The Problem Every Developer Knows Too Well You've been there. It's 2 AM, and you're staring at a wall of ESLint errors. Missing key props in React lists. Hydration mismatches because someone used localStorage without a server-side guard. Accessibility warnings everywhere. ESLint tells you what's wrong. But you still have to fix it yourself. The cost? Hours of manual fixes. Delayed releases. Production bugs that could have been prevented. What if there was a tool that didn't just identify problems, but actually fixed them? NeuroLint is a deterministic code transformation engine that automatically fixes over 50 common issues in React, Next.js, and TypeScript projects. The key difference? No AI. No guessing. No hallucinations. While AI coding tools can produce unpredictable results, NeuroLi…  ( 8 min )

I wanted something to work on over the weekend and wanted to dive into Web3 and also do stuff involving QR code generation (not really sure why just figured it might be an untapped market). After doing some looking online and asking ChatGPT what was needed in the world of Web3 it came up with a QR code based verification system for blockchain items and content. I spent some time researching the concept then started building with Next.js. The photos you see are the result of a few days of work (the back end and logic was 90% done by me with 10% Claude debugging. The design was all AI as I have the artistic talent of a cheeseburger). This is also working using the testnet for now as I do not want to lose funds testing. So here is how it works currently: Step 1: You sign in with you wallet (this is not stored anywhere and you will have to sign in each time) To validate, simply point your phone camera at the QR code and scan it. This will open up the validation page and show you if the QR code is valid or not. It will also show how many times the code has been scanned and the Etherscan link Why is this necessary? Traditional QR codes can be easily copied or faked. If someone counterfeits your product, they can just copy the QR code. There's no way to prove which one is authentic. ProofQR provides a way to make sure your data is secure and protected on the ETH blockchain. What I need from you is feedback. I want ideas on how to make this better and potential additions to add. Any and all feedback is wanted. Thank you for viewing my post. Stay tuned for future updates!  ( 7 min )

The move signals Amazon's intent to leap ahead in the intensifying competition to build AI systems capable of performing complex, multi-step tasks that currently require teams o…

Mistral AI, Europe's most prominent artificial intelligence startup, is releasing its most ambitious product suite to date: a family of 10 open-source models designed to run everywhere from smartphones and autonomous drones to enterprise cloud systems, marking a major escalation in the company's challenge to both U.S. tech giants and surging Chinese competitors. The Mistral 3 family, launching today, includes a new flagship model called Mistral Large 3 and a suite of smaller "Ministral 3" models optimized for edge computing applications. All models will be released under the permissive Apache 2.0 license, allowing unrestricted commercial use — a sharp contrast to the closed systems offered by OpenAI, Google, and Anthropic. The release is a pointed bet by Mistral that the future of artifici…

Researchers at MiroMind AI and several Chinese universities have released OpenMMReasoner, a new training framework that improves the capabilities of language models in multimodal reasoning. The framework uses a two-stage process. It first refines a base model with a curated dataset in a supervised fine-tuning (SFT) stage. Then, a reinforcement learning (RL) stage guides the model to reason more effectively in tasks that involve both text and visual data.  Experiments show that models trained with OpenMMReasoner outperform other leading visual reasoning models, often while being trained on a smaller, higher-quality dataset. The framework and all its assets, including a trained 7B model, are fully open source, providing a reliable foundation for building applications that require traceabilit…

Every data engineering team right now is being asked the same question: "How do we build a chatbot that talks to our data?" The prototypes are deceptively simple. A developer connects GPT-5.1 to a Snowflake schema, asks "What is our revenue?", and watches as the model generates a syntactically perfect SQL query. It feels like magic. But when these systems move from a sandbox to production, the magic collapses. The bot reports $12 million revenue on Monday and $9.5 million on Tuesday, despite the underlying data remaining unchanged. The failure isn't a lack of model intelligence; it is an architectural "context gap." Gen AI models are probabilistic engines trying to interpret rigid, deterministic business logic from raw database schemas. Without a mediation layer to define what "revenue" ac…

AWS is leveraging automated reasoning, which uses math-based verification, to build out new capabilities in its Amazon Bedrock AgentCore platform as the company digs deeper into the agentic AI ecosystem.  Announced during its annual re: Invent conference in Las Vegas, AWS is adding three new capabilities to AgentCore: "policy," "evaluations" and "episodic memory." The new features aim to give enterprises more control over agent behavior and performance.  AWS also revealed what it calls “a new class of agents," or "frontier agents," that are autonomous, scalable and independent.  Swami Sivasubramanian, AWS VP for Agentic AI, told VentureBeat that many of AWS’s new features represent a shift in who becomes a builder.  “We are actually on the cusp of a major tectonic transformation with AI, b…

The AI browser wars are heating up. OpenAI and other AI companies like Perplexity have gotten a lot of attention with their new AI-first and agentic browsers. They're being positioned as direct competition to Google, which currently holds a 70% share of the market with its Chrome browser. As the incumbent, Google has been slower to respond to the shift toward AI search — integrating Gemini into Chrome, is widely seen as playing catch-up to competitors that were AI-first from day one. It's understandable, as a $100 billion business is an enormous, unwieldy beast to pivot. That leaves space for the new guys to maneuver, who are essentially starting with blank slates, and free reign for innovation. Enter Neo, released for worldwide general availability today — the next step in Norton’s AI inn…

Amazon Web Services (AWS) is leaning into the growing trend toward custom models with a new service that it says will let enterprises bring more personalization and internal knowledge.  The move comes alongside the release of AWS's new models as part of its Nova family, which expands the capabilities of its reasoning models. Nova 2 Lite, Nova 2 Pro, Nova 2 Sonic and Nova 2 Omni update the first Nova models AWS announced last year. Nova 2 Lite is a fast, cost-effective reasoning model optimized for everyday tasks that can process text, images and videos to generate text. Nova 2 Pro, which AWS said is its most intelligent reasoning model, can handle complex tasks such as coding agents, long-range planning and problem-solving. It can act as a “teacher” model for distillation projects. Nova 2 …

For much of 2025, the frontier of open-weight language models has been defined not in Silicon Valley or New York City, but in Beijing and Hangzhou. Chinese research labs including Alibaba's Qwen, DeepSeek, Moonshot and Baidu have rapidly set the pace in developing large-scale, open Mixture-of-Experts (MoE) models — often with permissive licenses and leading benchmark performance. While OpenAI fielded its own open source, general purpose LLM this summer as well — gpt-oss-20B and 120B — the uptake has been slowed by so many equally or better performing alternatives. Now, one small U.S. company is pushing back.
